ADCs are pretty important
So important that you can have a support in the top lane and botlane and remove your jungler. So important, if the above is done, you basically have yourself a good game still and an ADC with infinite amounts of peel.
Done right, top laner loses CS - jungler is the only person to worry about. Toplane support can roam and their ally can freeze.
I find it pretty fun but isn't that much impact a bit too much.
