The answer isn't a nerf! Escorts need the firepower, they are an escort it is their job to hit hard and fast, And tactical captains if they have a means to heal then that makes life easier for those of us that don't pvp. My main character is an engineer I have a few cruisers a handful of escorts and the breen which is kind of a middle between an escort and a cruiser.
The answer is actually a buff to beams and turrets which MANY cruisers use...now I admit I'm not a huge treckie but from what I have seen an over-boosted beam should come pretty close to ripping apart an enemy ship. Watch your power levels as you fire all your weapons and you will see exactly what I'm talking about. notice the damage your weapons do gets lower and lower as your power gets depleted.
The problem is that Cryptic are not capable of changing things to make the game more balanced so the easier option is to just nerf Tacticals to bring them in line with Science and Engineering.
Trust me, this is within Cryptic's intelligence level, what everyone else is suggesting is not.
It seems to me that the even better solution would be for the character class descriptions to be updated so that people know what they're actually getting into. As it is people just go with whatever sounds "cool" or "trekkie" and only when they reach lvl 50 do they realize that scis in sci vessels won't be like janeway and use space magic to solve everything. We all know what scis are designed to do, we all know that having a single sci around that really knows their stuff can be an amazing boon, we all know that most of the time scis really want to be doing damage above all else so why are they scis??
Personally I really like it the way it is, it neatly sidesteps the trinity without penalizing specialized rooles. Not necessary but not a detriment either, how great is that? Why can't other game companies get that?
I don't know that nerfing is an answer. Tacs are already pretty bad on the ground in PvP and PvE. Space is kind of their thing. If they can't do so much there, there's really no place for them anymore. As an Engineer, I deal out hideous amounts of damage and am utterly unkillable in ground combat. (The same, to a degree is true of Sci, though it needs a bit more work to do it just so.) I'm not as needed in space. to me that's always just been how it is. Tacs rule space and largely suck on the ground. Engineers are amazing on the ground, not so hot in space, and science is decent but not showstopping, in both.
