This. My Elec Sentinel floors mobs. I can run solo missions without my resistance toggles running and barely notice. GM’s, AV’s and such don’t really work without help. Don’t really focus on it on teams because mobs melt to quickly. My build isn’t “optimized” for drain either. Pretty decent damage. Great regen and recovery. Fun toon. Something different than just SMASH!
Elec/Elec/Elec Sentinel is fantastic. I play one as my main/badger. The damage is fairly descent. Not blaster level but good enough. It is unbelievably tough. Added bonus, Aim improves your -end powers. It is a very fast sapper. Most mobs just stand around blinking at you with an empty endurance bar. Even Bosses. Enjoy.
Elec/Elec on Sentinels is awesome. I have two attack chains that floor whole enemy group’s endurance. A great hold. A great heal. Regen. Recovery. And decent resists. Baddies just stand there and blink at you while you pick them off.
