Boss destroyer
Overall gameplay: You will be mainly using melee to save precious Bolter ammo. Luckily this wont be a problem as this build has all the stong melee talents.
Boss delete
When boss (or bunch of crushers) become an issue. Use infiltrate, switch to boltor (keystone activation) and unload.
Low profile
I dont see many people run this, but I find it amazing to revive multiple teammates, get objectives done, and to just be able to focus on boss or other high priority targets while getting left alone by all the trash mobs. If you really dont want to use it switch for Iron Will for a great toughness boost.
