I think drop rates are a bit too low for the justice gear tokens
I don't mind working towards something but it's not very fun having to grind the same rampage for hours upon hours and often times have nothing to show for it. Sometimes a person ends up waiting half an hour just to get into a group. Getting justice gear is fun. Idling around the Ren Cen for a rampage to start for half an hour is not, especially with how often one has to do it in order to get the needed tokens.
The low drop rate makes the process feel closer to tedious and further from fun. I'll still end up grinding as much as I need to in order to get my justice gear, but I would actually have MORE fun if I had to run each rampage LESS often.
