Should include a poll. In order of my personal preference, Ryze would be next...mostly because I bought Tribal Ryze last time it went on sale, having forgotten it's kind of garbage and I'm hoping it'll be better when it gets updated. But I've got Dark Crystal Ryze to hold me over until then.
In terms of who actually NEEDS it the most, there's no question that Tier 1 in terms of clunky models consists of Kassadin, Taric, Sivir and Annie.
Followed in close second by Nidalee, Sion, Master Yi and Pantheon.
Everyone else is more or less in good shape. I've heard Shaco mentioned, for example. While he does look somewhat out of date next to present-gen models in terms of like, shading on his clothes or details on his weapons, he's at least in proportion. He doesn't have giant clunky triangle feet or a big sculpted-looking chunk of one-shade-of-black hair or anything that makes him an eyesore to look at like some others.
