Casual PvE gear progression would be pretty neat, but I feel before they add that, they need to re-do the entire loot/gear system. All the "ilvl" stuff and the numbers are confusing and way too high. I hope in the next expansion we get an item-squish, back to where people have around 20k-30k health average, like Wrath numbers. That would be nice. Also they need to get rid of ilvl, way too many people freak out about it and it is dependent, it just took the horrible add-on gear score and added it to the game, giving each person a "number" instead of their skill.
