So devs if you are looking for the BEST way to rework the GCS then just release Dontdrunkimshoots proposed 3 Pack!
Everything else is just a compromise!
The problem: COMPARED to all other crusiers (even Starfleet cruisers) the Galaxy class just got the short end of the stick.
Cryptic intentionally made it the enigneering heaviest ship in the game, knowing that Engineering will have the most passive (and boring) BOFF powers of all career branches.
And if that's not enough they gave that ship 3 science and only 2 tactical console slots (?), althrough it only got a Lt. Science BOFF slot.
All other ships can either tank better or be more offensive, because having 3 (!) ensign Engineering slots doesn't make sense since the CD of most Engineering ensign powers interfere with each other. If that's not enough, being so engineering heavy makes that ship extremely passive, even science ships have more means to become active in combat.
Having the least offensive potential of all cruisers in the game you can just hope to outheal your enemy, other ships can do that even better, if they have more Science BOFF slots. Even a T5 assault crusier can tank better since it has a slight?y higher turn rate and so has a higher chance to get an undamaged sield towards the enemy.
So in my opinion the T5 Galaxy has only drawbacks to offer, compare to all other ships in the game, and for a fan of that ship it is a real gamebreaker to fly it, because it just lack on all ends.
I would like to have a C-Store service (you may call it Mirror Galaxy Class or Galaxy Class Battleship) to permanently change the appearance of the (Fleet) Assault Cruiser retfit (regent or fleet regent) into a Exploration Cruiser Retrofit (Galaxy Class).
I think 500-1000 Zen would be sufficient since in order to use that service the player also has to posess both ships which are also have be bought from the C-Store.
Once that service is bought, the player gets a special (universal) console to install on the Regent.
Once Activated (right click and "use") that console changes the ship into a Galaxy Class having just the BOFF/Console Layout of the Regent.
All availlable Galaxy Class ship parts (like monarch or Venture class for example) of the players account get unlocked too, of course.
So compared to the "real" Regent that ship has following stats different:
Turn Rate 6
Inertia Rating 25
So except for Crew the changed ship has slightly worse stats.
I am sure many Galaxy Class fans would be ok with that in order to fly a "good version" of their favourite ship. If the devs think it is appropriate they also could remove the Galaxy's ability to seperate, i am also sure many fans would still be glad to have such a ship.
This Service/Console would be a complete fan service since as i have already said, the Galaxy Class is an exception because it is (unlike a T5 Constitution) Supposed to be a full T5 ship, but in game it is a real pain to fly if you are a fan of that iconic ship.
The inspiration is the parallel universe Enterprise -D from the episode Yesterday's Enterprise, which showed a much more battle ready and more badass Galaxy Class, at least not as rediculus and childish as the Galaxy -X from Q's fantasy timeline. Since such a ship would fit perfectly into STO i always felt that this ship should be in this game for a long time.
Additionally, Galaxy Class fans get the chance to have fun in STO and not just flying to most boring and lame ship in this game.
Cryptric could even sell some more Regent Class and Galaxy-R ship appearances, by just releasing one single console.
How much time does it take to crate a Mirror universe Version of a ship?
Not as much as creating a new one from scratch, i suppose.
This one also has to be bought from the C-Store AND needs to at least 2 other ships from the C-Store plus additional ship appearances. So i think this could be one of the most lucrative Mirror ship in STO.
And you know what Galaxy Class fans would buy it in order to get finally a fun to fly version of their favourite Ship in Star Trek.
Let's be honest no one really cares about canon in STO, since we got Carriers, Spacefighters and Escorts dominate this game, not to speak of almost no one using canon Starfleet uniforms. So if you consult canon or not, the Galaxy Class should be changed either way, all that it wouldn't make the galaxy Class OP, but it would make a lot of Galaxy Class fans happy.
Cryptic proved themselves with the introduction of the various mirror ships (Mirror Assault Crusier, Mirror Patrol Escort and so on), that giving a ship a different appearance won't make the game chaotic or unbalanced.
