Hireling Info?

[AngryMob]

hello fellow lurkers, this is my first post on this forum :D *yay* and i just have a quick question regarding mercs. i currently am playing a bone / summon necro, focusing on skeletons / skel mast. im wondering about trying an act1 rouge merc, just because ive never really used one other than in act1 normal (quest reward...yay.) is it worth trying? or should i just stick to the classic cookie-cutter act2 aura mercs like everyone else...
also if anyone has any sites with more info on mercs and their stats (more than what is on Arreat Summit,) i would appreciate links or whatever.

thanks again B)
