At rank 8 you lose 1m of rebirth timer iirc. Flaming pinion and # of people flared increases are a pretty big deal to people as well.At this rate Guilds will still be Useless. The only benefit being 1 or 2 things (gems and petty buffs)
Those that guilds that reach rank 8 get the bonus and the buffs and they lose exp if don't keep it up?
It was 4 months ago that Kingsman or whatever the name at that time reached Rank 7. So I imagine it's not going to be a change that happens soon.
