Well, I thought I would post an update for any who were curious or offered advice. I started a pyro powertech and ran with it. Right now he is just catching up to my mercenary and there are a few observations I will give here.
1. PVE the powertech does a little less damage and has a little less crowd control. However this doesnt really mean a whole lot as it is tougher and has more tools to deal with different situations. Thus far I have died a singular time with my powertech leveling to 27, my merc was not so lucky.
2. PVP, powertech wins, its blatant, and not in a subtle or small way. To offer evidence I will say my average damage/ match has increased by roughly 60,000, kills average increased by about 13/match with some high outliers and my objectives average around 8k where my merc typically had around 1-2k unless he sat on an objective.
These observations may be a skewed slightly, after all it is the same player and my pvp experience has been increasing quickly because I have just begun but to go from a record high of 146,000 damage, 41 kills on my merc to 285k damage, 65 kills and the ability to function in the objectives game more (good god I almost feel bad for the ball carriers I grapple in huttball...) is notable.
Thanks again for the advice everyone, both classes are really fun to play but the PT just shines through, besides burning everything in sight is a solid point of sale
