Yup. Priests, mages, warlocks will all be wearing the same robe with the same staff. Terrible idea.

Haven't you played since Season 1 became available for honor? They already are :P

Totally, because priest are all about spell crit and warlocks and mages love that mp5.

Best in slot gear is usually best in slot for multiple classes, this isn't going to change things.

I disagree - I think it will mean that there are 3 or 4 different pieces of gear that would all be good for you, so people will actually just take whichever drops and all look different, even within the same class.

I disagree, people looking the same wont be a problem as long as blizzard keep using a tier loot system with tokens, which I doubt they will stop using. All it will mean is that people may have the same bracers and boots, which dont make too much difference to casters. As for the same staffs, you can pretty much argue its the same at the moment, I think the odds are that the less diverse the stats are, the more diverse the range of gear will be.
