Shin'arika-
I have played with you every once in a while in the odd match with my 50 Shadow. I think last night even we were in a Civil War together. (Vudurlo) And I've picked your brain about some Shadowy stuff... which has been great.
I say this because I want you to know it is sincere, but I can't get behind a Shadow DPS buff. Could the trees use some tweaking? Heck yes. Big time, especially Infiltration which originally attracted me to the class, but sadly I rarely plan to play until I am fully geared.
The main reason I can't get behind a DPS increase is we have an intangible bonus that you can't put a number on: Utility.
The ability to do 'good' damage, stealth, pull a healer away from his team, debuff our opponents, mez from stealth, etc, etc. is simply amazing stuff for anything from solo queuing, right up to RWZs.
At times I do feel my damage is lethargic, but I remind myself I only have 2 pieces of Warhero, and 3 augmented pieces.... Then I'll single handedly disrupt a control point in Civil war, and I realize, DPS is THE wrong reason to choose a Shadow.
I'd suggest if someone wants to go the DPS route, and is willing to sac some utility, then try a Marauder/Sentinel, or a Powertech/Vanguard.
Personally I find those classes a bit boring, but I see the attraction of pure DPS. But me? The Utility is fantastic and always useful. It's also tough to put a metric on it.
Also as far as DPS boosts go, I have to be honest, whenever I've questioned it, I've been in a match with you and you do a TON of damage... even if you don't have your healer with you. I've often thought to myself, that the DPS I do feel I'm missing is obviously attainable through practice and gearing, and you are proof of this.
I think this is a very hard sell for you, but good luck. Heck I'd take the DPS boost if you can sell it to BW, but I think you're going to have trouble convincing them.
