You realize that if there was not a cap people would have been geared out in i90 within the first month and as soon as they cleared t5 dropped the game right? The little bit of progression people have now would not even exist and instead of the "some darklight", "relic+1", "full darklight and relic +1, blah blah blah shouts it would be "ilvl90 gear only or go home."

That, IMO, would be terrible for the community because we already have a gap and a purple elephant between people doing/clearing coil and people who just hit 50/starting coil.

With that said I think the leves idea is interesting and could be either really good or really bad. Depends on how many marks they would award for each completion and how long that grind would feel.
