A cool buff to Rammus

Hello - I was thinking about one of my favorite champs - Rammus - and a buff that would make his ganks much better!

Turn R into a toggle, lower the damage, and add "Grounded" effect. Allow R to be on while in "powerball".

Less damage on R would tune him down against melting towers. It would give him a third form of CC and make his early game much stronger, as well as team fight utility, outside of engage, and lockdown one priority target.

Thoughts?
