Well, in 2.x relics ended up being better than the last tier of raid weapons. Personally, I think the raid gear should have the better stats, but that's a completely different discussion. I'm just saying that all gear should have unique / complex stats, with harder to obtain stuff such as relic weapons or raid weapons having better stats. It still won't lead to gear discrimination, because going back to my original point, gear is already set up with some gear being better, having better stats, and people without specific pieces of that gear aren't discriminated against. Adding unique stats will not change that.
