I'm guessing you're taken this from the last night discusion when there was a lot of people online. We had many good ideas thrown out there such as the 3 already posted here which was the
1. +_ tokens gained per 10mins
2. -_% chance of wooden fragment drop (still sounds bad to me just my opinion)
3. +_% of getting socket items
Along with that there was discussion of
1. Getting rid of the new gem but instead increasing all tiers of gems by 1, making 3 perfects turn into a "priceless" gem with even higher stats
2. +_% Chance of getting a higher rare tier effect when unboxed
3. +_% to add 2x multiplier to stats when unboxing
etc, It's hard coming up with a new attribute because most of the main attributes are already in place, however i'm sure we'll be able to come up with something.
