I just started season 5 and wondered if the hammer build in S4 are still viable. I had alot of fun whit that build and a thorns build doesent look so cool(;
well it was buffed in damage and they added a new supportive legendary affix to hammer jammers pants, there were some ~80 gr clears on ptr so it should be viable-ish
From memory one of the top EU clears was a hammer build not sure where he slipped to now but he used to be top 5
hammer is viable but it's also squishier than thorns which in return means you have to fish more and earlier for a good grift.
