Just got Taowu alt skin and I was thinking on basing it on a 25mm base instead of the 30mm provided. It looks better to me (30mm base feels a bit "empty") and also it could be eventually usable in Infinity this way (providing he got a profile for Infinity. I'm not sure as I'm off the game by a few years now). Also, I see no downsides on using the model on a 25mm base in Aristeia. So, just for the sake of discussion, anyone could advice against this and why? Will gladly read and consider other opinions.
Aristeia! doesn't care about base size, you can use the 25mm, 30mm, a hexagon base, or whatever else you like. The main reason he comes with a 25mm is because he's also playable in Infinity, which does care about base sizes. Feel free to use it in Aristeia! as well though.
