I suppose it's all down to party roles. My total DPS was stratospherically high but the Rogue's single-target damage let him take out enemy leaders and the meleer who broke away from the tanks, the Druid was shoving people around like no tommorrow, and the Paladin/Fighter kept things locked down. I has just thought of the 'kill everyone' role as the Striker, not the Controller.No, adding your implement bonus is specifically intended.
You should not allow yourself to be talked out of your bonus. Playing a wizard can be hard enough. If the other players can't keep up, then perhaps you could help them making the best of their class.
Of course, if all other players play Defenders and Leaders, then you're supposed to do the most damage.
The Striker's role is best expressed as "neutralize the key target as efficiently as possible". That usually translates to "kill the biggest threat fast". The Controller's role is to disrupt and counter enemy tactics. When enemy tactics involve close coordination and/or masses of enemies, that often means "do a ton of damage to the enemy even if it's not that much to each individual target". Controllers are easily capable of dishing out the highest amount of total damage--they're just not the ones who rapidly drop the priority targets.
