I run a server myself for some friends and we ran with 2x EXP rate and our drop rates are roughly 25% higher than the original game. We also did a bit of redundancy cleaning up in regards to what drops for what Section IDs as well (and added items to the drop table that could only be obtained from events we didn't have.) That's probably a bit too ambitious and it took quite a while, but I definitely think a slightly accelerated EXP gain would keep things a little more arcadey and refreshing.
