Banner of command and how to balance
Return banner of command and make it have 70% damage reduction again however, give it the scuttle effect
hard CCing it removes its damage reduction for 5 seconds
what this means is the counter to scuttle is now CC+damage instead of just trying to out damage its damage reduction
a support and adc can get rid of it easy, mages while having to use their CC (which can be part of their burst) can also get rid of it, and a support can defend vs a banner by CCing it while its being attacked by tower, to make it die faster to tower.
its a simple fix, make CC the key to making banners killable
