I control Frenzy Plant. If you want to have a character join, that's fine, but I'm not retconning guild history to have your character have been part all this time. I definitely can, however, arrange for your character to have been part of one of the 'branches' of Frenzy Plant and just now decide to throw his lot in with the guild proper. That's be perfectly acceptable and a nice angle for outward development. Currently Frenzy Plant is on a mission in the lonesome, haggard town of Belka in the mountains, known for its medicine but said to be harboring refugees from some sort of plague in distant Eigenalle.
Overwatch is pretty fun for me, and all future content as in heroes and maps will be added free of charge according to head of development Jeff Kaplan.
It wouldn't be quiet if the players with characters in Frenzy Plant responded to my most recent post giving everyone something to do specifically (not you Oblivion or Caits, kudos to you two).
