Wow expansions normally have crazy gear jumps, to accommodate all players. Easily quested gear often out weighs the previous expansions raid gears.

If 2.2 was an expansion for example they could be accommodating to those at 90, and make content suitable for that ilevel and leave out lower ilevels. Or they could accommodate to ilower-levels, and make it faceroll for 90's. The best and fairest solution is a harsher than 2.1 > 2.2 gear reset.

I do agree that gear should have been lower in the ilvl jumps though, maybe in 2s or 3s. I think 3.0 may come at around i150-160. And hopefully they will learn from Wows upcoming # squish....
