having monster that is killed every 5 second for 10 minutes is not how the game work, under 49 it's simply chain exp max. the trouble is the pop really really fast.

outside, in the world if you can keep up until chain 6-7 is nice, there if is done well you can get a pretty high number.

by the way, you know that Fate where you grabs items from monster and around is the same pop? strangely no one is trashing you when you turn your item.
