I wrote my comment about the fact that it shouldn't be available in ranked while it was suffering from glitches (it wasn't able to be killed at all at one point). Is this all fixed?
Tell me if I'm wrong, what if the commuter can choose whether or not to roleblock? There could be "commute?" option for the commuter, which means that anyone who visits them will be roleblocked. Then the commuter can decide whether to roleblock everyone, but miss the chance to get gunned or investigated, or not roleblock, but then run the risk of being killed. It could give this role more versatility and be less annoying for mafia and town alike. Tell me what you think
