The Mask energy field is a rather interesting gimmick but i have always found it rather usless on any of my KDF ships, and rather impossible to use on carriers. Stealth in general wither it is any cloak or MES, generates quite a bit of agro against NPC especially the EBC, but the MEF is just the same a MES as a poor mans cloak which brings the short coming of not actually being cloaking. Add into MEF being a out of battle cloak renders it unusable for carriers since they are practically always on red alert due to the carrier commands leave them in that status until toggled off. As it stands that stealthing systems cannot stack any more since a little before or after launch, having redundant stealth systems is rather stupid now since most of the KDF ships comes with cloaking or better, and if some one needed/wanted cloaking they would obtain MES on the ships that didn't come with cloak. Even with the current bug where allied ships in the field will remain stealthed while firing the ability is still rather useless and only useful in an organized PVP group in a PVP environment.
STO is a game that requires a constant stream of DPS and limiting a players DPS due to the sitting there trying to make use out of this power isn't exactly a good move so in luau of the short comings i stated, I move that this power be reworked to something more useful or exchanged for a different power.
One upgrade to the power would to make it a sort of Battle MES with a field atrubute: Lower its stealth rating add in a power drain of 25 aux to user, tone down the defense buff, put user in red alert, fix the issue of allied ships being cloaked while firing, while the user is firing any abilities launching any craft or shooting any weapons will drop the MES on them self while the field stays active until disabled by user or others(aux offline, shockwave, tricobalt, viral matrix, and SNB).
Another thing would to remove the power completly and replace it with another deflector cannon like the MACO set has, or a debuffing torpedo like the Omega, or just some completly different power that can be used while in combat.
Or just leave it relatively like it is and allow it to be stacked upon any cloaking or MES while nerfing it slightly to balance it.
I disagree with your post completely. The suggested material would make the set and skill completely unwanted and put anyone using it at a serious disadvantage based on how it was designed and what it was being designed for. All I'm going to say now is that if you are a KDF player and wanting this to be a better ability you are going the wrong way with it... Reducing stealth reduces its stalking ability which is whats its designed for, as well reducing auxillary is this making it weaker and killing off your power of science abilities. I could go on but the point has been made. I'd like to see it improved but based on a wealth of knowledge I have on these abilities its just not going to fly with me.
The minus 25 aux power was a proposed balance suggestion to bring it in line with the whole "this power is on till you shut it off or is forced off,even during combat". Also toning down its stealth so it could be running while any other form of cloak or MES is activated was another balance suggestion. Its not like i want to leave it as is then tack thoes 2 features on only for people to whine OP, there is somthing called "give and take" and STO does that "ALOT" ex: phaser relays, you stack 3 of them on your ship the game takes away some points so you dont recieve full benifets from having multiples, or you put the same power on a Boff or spread across 2 Boffs and you come across the fact you could of used a different power and the global cooldown activates on use , little things like that that brings equality and ballince into the game.
I've actually used MES on a Karfi in Pvp. Sorta interesting you used to be able to get off an overload beam attack before they knew you were there. But that was a loooong time ago. Really as a KDF player if your looking to stealth a carrier all I will say is best of luck and I'm not sure exactly what you are after. What really drew me to post here was.........
isn't exactly a good move so in luau of the short comings i stated
If there's a party i want an invite. Thank you in advance and I'm glad I could help.
