Right, except everything that you list (except varying body-weight, which no RPG currently accounts for, because that's ridiculously hard and overly nitpicky) is already accounted for in the system you're criticizing. And you forget that attributes in WoW play a role in things like Haste rating.
Instead of criticizing another game's system you clearly haven't really understood, why not wait for us to find out what this game's combat system will actually look like?
By body weight I don't mean measuring on height and race in nit-picking detail. An average for a species on its own works for this. I understand WoW's attributes after playing for... too long. I know they can influence haste, but haste is still a stat with no meaning. It still exists only for mathematical mechanics, to make the system work properly. There is no reason for it to exist otherwise. It is not your speed, that already exists as a different stat. It is not your reaction time to anything, that's in different stats. It's just a weapon swing speed modifier (as well as being a modifier elsewhere), that happens to have influences. Even with these influences, the sources are limited. I want something more to this than that. More influence. More variety.
I am more than willing to wait to see the games combat system before I make any judgment calls, but hopefully I can make it until then with people being a bit less offensive just because WoW was mentioned.
P.S. Ultimately I just don't want a WoW clone in terms of combat. It's boring, slow and a lot of it becomes a rotation. PvP might be a bit different but I find most people to be doing the same things nearly every time.
