Klingons have 4 ship choices at BG5, Feds have access to 6 choices at RA5. Half of the Klingon ship choices have 1 fewer bridge officer than all 6 Fed choices.
Access to the same equipment is somewhat disingenuous, but you might be too new to understand. Until Season 1 Klingons had enormously limited access to equipment - even the PvP venders were broken for MK X gear. Feds have long had a variety of options for access to better equipment, and still do today.
The basic ship stats are not the same, perhaps you need to take a closer look. Federation Cruisers have 39,000 hull, Science ships have 27,000, and Escorts have 30,000. A Bird of Prey has 24,000, a Raptor has 27,000, a Klingon Cruiser has 36,000, and a Carrier has only 28,000 hull - 2000 less than a Fed Escort!
The Carrier is the Klingon Science ship, but has a turn rate of 4. The powerful science abilities are forward facing, meaning it is not easy to use them with a Carrier. Where were you when Feds were crying about the Galaxy class only having a turn rate of 5? Big Fed ships were upgraded in turn rate - but not the Carrier - which still stays at 4. The Carrier depends on NPC fighters/siphons etc.. which will operate at "normal" difficulty after the patch. Hmm..
Fed Escort Captains have the choice of an extra Engineer OR extra Science bridge officer. Fed Cruiser Captains have a choice of an extra Tactical or Science bridge officer. Note that means both Cruisers and Escorts have the choice of an extra Science bridge officer - and tier 1 science bridge officer skills are the best in the game. Klingon Cruisers have no choices, and are required to have a 3rd Engineer bridge officer - while Raptors have no choices either and are required to have an extra Tactical Officer. Too bad for Carriers and BoPs - they only get 4 Bridge officers which is, as noted earlier, one fewer than EVERY Fed RA ship.
There are ZERO options for an Ensign science bridge officer at BG level for Klingon ships, even though Hazard Emitters, Science Team, Polarize Hull, Jam Sensors, Mask Energy Signature, and Tractor Beam are all viable Tier 1 Science skills available to Feds - not Klingons.
If you think all things are the same, then you aren't paying attention. It is clear as day there are a number of specific details that make each ship type unique.
The variety of options on both sides are good for balance, not bad for balance. Explore the variety with more depth and you will find things are about right. The only places in STO where balance doesn't exist is where the options are limited - like countering certain very powerful abilities. As more options for countering very powerful abilities are made available, these powers will be more balanced.
I personally don't think cloak is overpowered, but I also hate the nerf the DEVs made to stealth for Tactical in ground PvP - and I don't even play a Tactical character. It isn't overpowered if there is a reasonable defense, and right now (at least for me in my Star Cruiser) I feel like I have reasonable defensive/offensive options against cloak that can make it painful for the cloaked guy (you really need to read up on options for detecting a cloaked ship if it is that much of a priority).
If this is stil the case. Then all you have done is support the fact there is a balance issue. If the majority of Klingon BG have worse weapons than RA amoungst other equipment and can still over power the Feds then you can hardly say there is not an issue. I have had extensive experiance now of Fed PVP and am pretty good at it. However the numbers speak for themselves. Klingons winning almost every fight?? but no blance issue?? come on. They new SCi changes on Tribble should make a difference and balance things out but i still personally feel that Feds ability to detect clock, even at a v short distance needs improving for all classes. This would go some way to stop the gankfest. It will also help the Klingons as the Fed will not have to forum FedBalls constantly just to not get killed.
Problem is most Klingons know about this embalance and don't want it to change, that's why they are LOUDLY denying it everywhere. Some believe in the delusion so bad they encouraged me to fly my own BoP, that's when I realized it's worse than I originally thought.
If they were to actually balance PvP, most of these WoW players would quit without their IWIN button.
Even in a pug you can beat the klings, the problem is there are so many scrub players out there that don't actually take the time to learn what skill combination and what ship builds work the best and then there is the major issue of not knowing or not caring to work together.
I have been in pugs that actually worked well together and coordinated their attacks and healed each other and would go 15-0 against klings, then you get the pugs and are uncoordinated and don't heal, except themselves and have crappy damage.
I;ve said ti once and I'll say it again....
Rule #1 - don't PUG it is a waste of time. If you Must PUG because you for whatever lame reason do not want to joina fleet or a premade group that uses teamwork and strategy together or you simply never learned to get along with the other kids in the sandbox; then When you get into a PUG start by saking if the team you are in would like to stay together after the match and rework B/O skills to compliment each other better. If yes....then go work out a group dynamic that will allow for a counter to the Klingon alpha strike.
Rule #2 - captains need to know their role in a 5v5 map. Sorry to all the cruisers but your PRIMARY role is not DPS it is healing, escorts need to have some healing abilities to help the team out as well, Science is there for many reasons either shield healing, CC, a mix of both (IMO a waste of time build) and to buff and debuff.
Call me crazy but we are playing an "MMO", which means that massive multiplayer online game....if you do not want to get in a premade or a fleet team or even a friend team that you know you can count on then expect to get rocked each match and don't bother complaining on the forums about the klingons.
Fact is klingons DO NOT have to elvel from PVP but most like to, they have the alpha strike which means in theory they also have the time to coordinate attack strikes with or without VOIP.
Sorry to say bud but I do not PUG 5v5 maps its a waste of time. Go to CnH maps if you want solo style gameplay. SOlo builds flourish there.
Again i recoomend that you go watch our PVP vids you will leanr alot about pvp
