Is Liandry and Rilay better than Rabadon and Void Staff for fiddle's ultimate?

Answer: zhonyas and abyssal

source? in my experience, Liandry and Rilay is much better.

liandry's is a poke and anti tank item. you wouldn't want it on a hard engage champ like fiddle unless you think you're going to spend an excessive amount of time poking the enemy team with your crows.

I think it's good to get Sorcerer's Shoes, Zhonya's, Rabadon's, Abyssal, and Void Staff with him, or something similar to that. Should do a lot of damage. Why bother with a mediocre slow of 15% since it's aoe and a DoT that's only going to last like 5 seconds at best? And those give health which isn't a very useful stat on Fiddle.
