Probably wouldn't be for the main champions event but I think it would be a cool idea if a team could ban an agent or so each.
It would create variation in every game, make coaches and IGLs even more significant as they would have to think of more ideas on the spot rather than beforehand.
Like imagine, Ascent but one team bans KAY/O and another bans Jett. It would create uniqueness rather than seeing the same old Ascent every time. Thoughts?
