Nunu in General-ish, I guess

I feel Nunu needs a bit more damaging abilities, for people who want to play him mid, so I propose his Q deal damage to champions based on the heal he gets from eating minions, not the 1000 true damage. This is based on me playing mid and not being able to do much but use my E to hit them and speed boost someone to attack. Thank you for taking this into consideration! I also would like for a visual update on Nunu and also Nathan, because they don't look that good in game
