The thing I dislike about ilvl is that it is like a level. Of course when you do content designed for ilvl 210 in 230,250,or 270 it will be easier. If everything starts getting synched down they might as well start world battle scaling. Which ESO is doing now and GW2 does. I would probably play even less myself if that happened because I dislike the idea that regardless of how I progress, the game limits my progression.
