I'm not complaining about the performance of the current Cocos2d-x runtime but I think many projects (including the one I'm working on now) could benefit a lot from something like CCSkeletonAnimationBatchNode... Has someone tried implementing something like that? If not, do you agree that would be a good idea?
I think it is quite common in many games to have multiple instances of the same type of character. Since all of that animations are probably using the same spritesheet, batching seems like an appropriate optimisation.
