Ok, this question maybe looks silly but my raiding main is melee type and I just come back to my alt short time ago so I dont have much experience with casters.
I was running with http://www.wowhead.com/?item=50210 and http://www.wowhead.com/?item=40192. Today drop for me http://www.wowhead.com/?item=50273. Both weapons have the same item level, off hand is crap from naxx. I will loose around 65 sp (45 if I will use staff ench) and some crit but I will gain more haste. Also I will raise my hit with this staff (308 hit rating atm without staff). So what is better, 2h or 1h + off hand? If this matter I play affli (destro is boring for me).
Also if you have 2h weapon and 1h/off hand with the same item level what you would use (we assume you will be hit capped with both)? What is your preference and why?
PS: Sorry for bad english. Its not my native language.
