The return to sanctuary event and the boosts given to returning players are very useful, but I think we could add even more. The supply of Keys and Normal Gems still feel very low and none of the catch up mechanics feel like they help much.
In my opinion, doubling the Keys from Iben’s and The Assembly would go a long way. Additionally, I feel that rank 2 normal gems should be dropping in Inferno. Both of these changes would help players catch up while still leaving plenty of room for whales to continue chipping away at the Legacy system while the devs ponder the gem compositive system.
