Sry for spamming your post, but I am interested in whether you have tried the "normal" hex purge build with obsession, meph etc. For pvm I can't really see how bowlock can beat this. Purge you get huge life, res and fhr from obsession, more skills, high "ias" since 125 fcr bp is reached easily, pierce, way more - magic res, can use insight merc... If you played both, I'd like to hear your thoughts on the comparison. Only thing I can think of in favour of bow is more range (which is not an issues for es tbh, range is fine) and leech
It's pretty similar, I guess hex purge es has better aoe/screen clearing and they both really suck at killing bosses.
Bow lock has really good sustain and really good on a budget tho.
