Good ol' blocky. Only good against flesh though, Ravager still takes it for all purpose cleaning.
Blockhead does pretty well on most everything... except loaders and armored enemies.
Been preaching this since Day 1. lol
Yeah, I used the Blockhead to take down The Warrior on my first playthrough, where after mutliple farming attempts me and my friend got Conference Calls. We used those to own everything in TVHM. I was a surgeon with the CC ... not that it needed any degree of accuracy, lol.
