You are getting schooled by a random player @m0r0s who is able to do the proper math, which you seem unable to do. This post is a huge embarrassment!
I will not support this proposal unless you include the changes mentioned by m0r0s!
This proposed change does only benefit 2% of all players at max. Lower level guilds will never be able to catch up, if this gets implemented now without lowering the guild store level requirement. But maybe this is what you want to achieve with this proposal? Farming the noobs with your golden max level gladiators while most guilds don't even have upgraded the store to level 6? BIG YIKES!
