My 2 cents on the whole new vs old art discussion that keeps cropping up:
While I prefer the new art overall, I still really like the old art. With that being the case, I just think it's ridiculous that there isn't a toggle that lets you choose which style you want. Even if you don't get all of the new expressions they've been adding due to the artstyle changes, there should be a setting that lets you jump between the two.
The only time I think raw taking away an option is okay in any kind of game is if it breaks the balancing and they can't find a way to fix it the way they'd like.
As much as I'd prefer old face, choosing to support both art styles would be really poor decision.
It would unnecessarily increase complexity of the code, increase development time, increase time of fixing future problems or adding new features, and add new bugs (since code became more complex). Furthermore, it would be either extremely hard or impossible to make cimpatibility code that adapt old layering to new without redrawing old layers. And if you want to redraw them, artist workload would also increase.
For me it would be way more rediculous if they have actually decided to implement that toggle with the team of two people. Let's go, +1 year ETA!
