its a good sounding idea, but this is an mmo and as such, you will have many different skill levels, hardware levels and participation levels. while I wouldnt mind running something with a group of, in theory, equally competent/geared players, it starts to lent itself to elitism, which I think is bad and never a forward looking option in any mmo.

once you start introducing mechanics to reward the top 1% then only the top 1% are able to get them, and the disparity becomes even worse. since to get the rewards, you already have to be doing things at that level, which is impossible without the rewards...see where that is going?

would it be nice if everyone had the same drive and skill, of course. but its more of a dream than a doable reality without ruining what the game currently is.
