Micropatch is out! Rammus getting big buffs (he dropped 9% after W non-recursive). This'll be more healthy for him long term as he doesn't go infinite with large AR/MR things we add Seraphs bug fixes (shield was activating on taking 30% HP as damage instead of at 30%)

Not mentioned by Riot, but Ornn's passive bug applying on his base stats has also been fixed and is live in game (just checked on EUW live).
