When you say raw damage, what do you mean?
Actual raw damage? Sent Fire Blast (69) > Tank Scorch (50.) Sent Flares (52) < Tank Fire Sword (75.) That's T1 vs T1 and T2 vs T2. Sent damres debuff will help some.
Or do you mean raw kill speed clearing everything? Sents cause scatter, like a bad fart. Tanks cause clumping, like kitty litter. Tanks win by a landslide on clear all kill speed.
My shield/nrg tank sits around 2:45 for pylon times. I don't see any nrg/* sents pulling that off, (my fire/bio sent doesn't come close,) but then again, NrgMelee buffs + tank overbuffing vs sents generally being a poorly designed bag of crap, fun or not, isn't a very fair comparison. (Why don't sents get shield again?)
Been running Mr. G's arc at max diff with my fire/bio sent. Several faceplants but got through carnies, Crimson Revenant and family. Slow going of course. The tank rolled through all that without issue while being safer, faster and vastly more efficient.
