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).
Notes of the micropatch:
