I've played on a team with everyone there but defy (whom I've played a few pugs with) and I can safely say this this team's mumble will be filled with fun times.
Seymour will be screaming that he's a duck while novice simultaneously asks *your name here* for heals in exchange for a butt touch (can confirm he does in fact touch butts, met him at LAN). With all this happening defy is probably hitting some sick double airshot as a scout sneaks through to kiss Mike on the cheek; queue the "defy stop being bad" (love you mike <3). W, Seven, Robyn will probably just sing in mumble the whole time while holding down her namesake key all night (she makes it work don't worry).
On a more serious note, this team has some players with a lot of experience in this game and I'm sure it'll be a fun ride for whoever jump on board.
