I main Titan arc top tree with mida and a side arm, have done since d2 dropped and I wanted a change from the bunny rabbit on meth game style.. warlocks are just pve for me.. what am saying is I play solo 99% of the time and do quite well, apart from the stacked felwinters mob pop up in my game.. just keep moving in quick play and never ever stop looking at your mini map see if anyone comes side on. And if all else fails just shoulder charge the shit out of people
