Tempban in YG? Would be great because I've used it before when I had a server. It's actually a good thing giving "tempbans". Also if it's for Lv>=(Greater|Equal)5, it must be Max:7 days. Would be really good.

And about the speedbooster, well it must be there for player. But Sfa, Lva and Lsa, it must be disabled. Like if player press Speedbooster button at those regions/area, it wont give any effect. If there's no speedbooster, I'm pretty sure that it will be a bit tragedy for normal players.
