I nominate Evuo (in-game name T-elos)
Quite simply the best powertech and one of the best players to play this game. Knows all specs inside out. Has submitted countless bug reports and posts on fixes with statistical backup (check his post history).
He is also possibly the only powertech left in any server who plays (and wins) high level ranked games as dps.
There is no-one better for this role than him.
I forgot about Evuo. Thank you for bringing him up. And you're right, he would make a great candidate.
