I don't see the problem. Is just a number. If the ywant reset tiem level ok. But et the stats as they are. The probem is, the stats are calculated on base item level, so, that means reformulate the entire stats grow. I prefer let is as is now.

About the horizontal progression, will have more inconvenientas than advntages. Let's say you stop play at ilevel 300, then log in again after 2 years, and you find the current item level is still 300. For you is great, your item level is still revelant, whicis good. But, what if you're one of those who played those 2 years? You will play 2 years with the same item level? For me of course not. I want a increase. It is better a hybrid system. Item level increase with echa patch, but isntead of have only 2 sets of a item level tiers (for example, now is 2 set of 250, 1 setof 260, 2 for 270), we can have more sets in each tier. But, without stop increasing item level.
