Been playing a PT since Feb with some Battlemaster stuff, it's been by far the hardest character to play. Lots of abilities than need to be timed right and with PT build I am always getting into Heat problems. I agree it's a good class but it requires a skilled player, it does not suffer fools.
I need to really concentrate to do 250k damage, kills are always high because of the bursts.
My Sorc is lvl 41 now and I can do 250k damage in my sleep with her. It's so so so much easier.
Another problem with Powertech and any melee class that no one ever seems to discuss is the problems you get into with a crappy computer. Yes, I am playing on a 286. Without high frame rate good luck getting up close and personal. I use Iron Fist templates most of the time just to jet jet charge so at least I know my first hit is going to land before they warp away. Powertechs look funny setting off flame throwers when no one is there.
