I didn't want to believe the rumors and posts, but it is true. Warlocks are next to unplayable in pvp, especially in comp.
I play mainly titan but I'm also good on my warlock. It was quite surprising to see thaty warlock was in case survivability, movement and ability balance very weak.
I play with 6 resiliance, got almost killed every time 2 hit (except the shotguns), my buffed grenades doesn't even bring someone close to death and melee tracking and speed is inherent broken.
Bungie, for penumbra, please target to fix warlocks. Make their melee faster, their grenades stronger and their movement better.
Warlocks are not trash at all. I got my last word on warlock, my luna, currently all quest steps for redrixs broadsword with a warlock and keep a positive k/d. Just how you play the damn game.
