Ok, first of all.... get a grip.
VI do us all a favor and make the items class specific... would solve aot of problems, make it no drop, solve more problems.
I have lost 5 rolls on RBGs ALL to casters.
First of all, any caster, like the <edited> druid below... should never roll on this when a melee is there that could immediately use it.
Say a 15 wis belt drops that's all all, but no hast, and no AC, and you're a druid/cleric/shammy, and you lose to a warrior? Would you be upset, I am sure you would, especially when the warrior turns and gives you a tell I'll sell it for 50K to ya. Yeah right, you think I camp these items so I can buy them from you? I don't think so.
If the item were class specific and no drop would there ever be any contention? NO!
So please, don't be greedy, remeber there are plenty of people out there that have worked long and hard on their characters and could really use that item. So don't be a jerk and play that high and mighty role. It should be NBG... if someone can use immediately, then they get it. If not THEN it should be an all random. End of story.
