For the longest time ever, I stuck with pretty much a similar build. Shotguns and close range weapons, usually with skills aimed at the berserker, and all was well. I like playing Ao100, and usually I find all I need. Sometimes the Jackhammer, sometimes the butcher's cleaver. If I'm lucky I'd mod a nano shrapnel from a super shotgun and slowly but surely kill everything on the floor. And on a very lucky run, I even got to wield the Dragonslayer (unfortunately, I didn't find the berserker armor). However, a long while back I tried that on Arch666 on Hurt Me Plenty and I saw the fatal flaw on what I've been doing. It takes way too long to clear a floor. Not to mention it was noisy as hell blasting a shotgun from a safe distance.
So I went and tried pistols first. And I gotta say it was a ton of fun using gun kata. I can clear crowds of enemies at such a fast speed that it felt too easy. Though my previous encounter with an agony elemental soon showed some problems, it was still a ton of fun.
Of course, not having the screen on a near-permanent berserk state of red-ness was good too.
I should start trying out other weapons as well. Maybe rockets or energy weapons on my next run. Any suggestions on a specific weapon build for fun times?
