It makes me sort of chuckle whenever someone complains that they can't invite a specific player because their name is too difficult to spell.
For instance, if someone's requesting to join a stage through episode chat, all you have to do is click their name in the chat box so that "/w *character name*" appears, then just replace "/w" with "/si" or "/invite." Easy.
I find it annoying when people try to get my attention in a stage. They spam "hey!" or, in my case, "sieg!" while I'm busy fighting and obviously not afk. I don't understand why they need to check whether I'm paying attention, when I obviously am. They should go ahead and say whatever it is they want to say. I can't think of a good reason why someone would have normal chat filtered out during a stage and then require that kind of persistence to communicate with them.
While I'm at it, warn me before resurrecting me, plox.
