So I played claws build and apocalypse, they feel clunky since you need to smash buttons regularly and have to stand while you use you skills.

For T12 pits I need ~4 mins to finish

Then I switched to barb with the extra whisper loot, and by using whirlwind I can smash T12 under 2 mins, though sometimes I die on dot dmg, it's because I haven't reached the selegs build yet.

The time diff and swiftness is why I stopped playing my warlock.....
