»Nah, Ragnarok from Olaf won't save him from Defile/Skittles, he would have been melted away since he didn't have any MR I don't believe. Ult only gives ~20 if I recall. Olaf should have charged down mummy so he can't lock up Vayne while the rest of the team gets Karthus down as quick as possible. That's how I would have played it anyway.
he had a FoN and tons of health, charging down mummy obviously didn't work out as pretty much everyone agreed that he should have focused someone else in team fights
