Well, how about bringing them back, but also revamping them in the process? Have each and every Chest contain a guaranteed, Bind-on-Pickup Rare or Epic, but with the caveat that each Chest also has a Level-Requirement to open. I'm not just talking a minimum level, either; also have a maximum-level that can open it. That way, players don't just start farming them with their higher-level characters. In fact, if you aren't eligible to open a chest, don't even let the player *SEE* the chest, to avoid people making "scouts".
Honestly, I just think the game could really use a bit more excitement when leveling, and I think bringing Chests back, with infinitely more powerful loot, would go a long ways towards that. Like I said, put a bunch of parameters in place so that players aren't able to monopolize them, but I really, truly believe this is the exact shot-in-the-arm of adrenaline that the leveling-game could really use.
