I would like to give a shout-out to Garjida
He is a Jedi Guardian who uses tank spec but he hits like a truck and is damn near impossible to kill. I can recall in a Huttball match the other day him leaping to me and forcing me to run back towards the ball spawn where everyone was fighting instead of letting me just afk in the pit. He chased me all around that game and I could never take him down. This guy is seriously a B-O-S-S. Anyone who sees him coming should just run, not that running does you any good since he can just leap to you.
List of Best Players Rep Side:
Commando: Riddic/Rafter Badger (Both Amazing and awesomely geared)
Sentinel: Drazzen/Eroh (They're both awesome and both need to be mentioned)
Vanguard: Kitt-eh (Not sure if they still play)
I'll update with Imps later.
