Can the new Willump not sound like an old man saying "Roar?"
I'm not talking about the little brat. He's fine. But the voice actor of that yeti literally didn't even try. It's like you told him, "Okay, Homeless Bob, just roar a few times and we'll edit it later." "Roar." "Okay, thanks. Here's your $2.50."
If the frog in Kai'sa's taunt said the actual word "Ribbit" three times, you'd eventually stop using that taunt altogether. If that frog had a bad voice actor and was forced into speaking every time you perform a minor action, you'd have second thoughts about playing Kai'sa in general.
Please. Remember when you reworked Pulsefire Ezreal's voice lines, but still kept him as an over-hyped legendary skin with nothing new? Your excuse to never give him the rework he needed was because you gave him a shit rework, and that was apparently good enough. Don't do the same thing to Willump.
