The implementation of a cancel button in PVP is long overdue, but I could be mistaken. I understand there is no cancel feature after the final selection of moves in the “traditional” VGC formats. Still, the most similar comparison to PokeMMO (in my opinion) would be Pokemon Showdown, which has a cancel move feature. I don’t know whether this will be implemented in the near future or has already been discussed and voted on. I know many times when I and many others have misclicked a move by volition or an error in keyboard inputs where the game's tide alters, resulting in the loss of a match. At the very least, this would limit unintentional mistakes, add an additional balancing mechanic to the game, and make PVP more stable and less RNG-reliant, if only by a slight margin. I'm a noob so go easy on me when roasting.
