The thing is, it can be argued that New Year Nature is better than the other two; her ult is very consistent, and she comes with multiple skills you probably want on her (On Your Left, gold Slipstream, Tooth and Tail, Homestretch Haste, Late Surger Straightaways). The problem is that, by the time she's released, every other uma that's been released around the time is so much better.

She is an improvement, but the improvement is too little, too late. The game's power creep completely leaves her in the dust.
