Xat has announced that the next power will be group power BLASTBAN. Using simple deductive reasoning, it would seem that since blastPRO was linked to PROmotion animations, blastBAN must be linked to BANning animations. That is, blastban will most likely be a power that produces chat animations whenever a user is banned. If this is the case, we would expect that a user will be able to select from a few such animations; just like blastpro.
