Please stop reverting Nunu changes and just give him a buff already.
He needs it more than any other champion. Nunu is the laughing stock of junglers and the only support jungle in the game. He should always be a viable option but he's just plain garbage. The new jungle items allow basically any champion to clear somewhat well, and the most common junglers just blast through the jungle without needing more than a couple pots on the first clear. After first back they clear faster than Nunu, have better ganks, and better carry potential.
Nunu has had several changes on the PBE in the past few months. One of them was for the most part a nerf to his blood boil which was thankfully not put through. Another change that has been on the PBE at least twice was an increasing slow on his ultimate. It's been reverted at least twice. The most recent blood boil buff was also reverted.
Please just prioritize giving him a numbers buff or small mechanical change like the recent blood boil rework. He's pretty much unusable in high elo and it's just painful to see his buffs get reverted time and time again. We've known about the increasing slow on his ultimate for like half a year now and it never reached the live game.
tl;dr Nunu has obviously been on the radar for months so why aren't any changes making it to the live game? He is like emergency-level unplayable.
