I dont care about the perks i have to use i care about the nades witch hardly kill one out of 20 enemies without the smoke. Titans are extremly fast with their meele you die when they hit you first and warlocks have a 1 mile auto aiming meele so I dont think its unfair or something like this. If any class hits you with a nade you should habe a problem and without the smoke you can just walk away
