If a player is a substitute and they don't go to worlds, but their team wins do they win worlds?

Well they were a part of the team...and did help the team in some way reach that title....

I dunno. First thing that comes to mind for me is if WXZ - the owner of IG who played one game as an active member of the roster - considers himself a world champion having been even a mere portion of the success.

its kinda like in the NFL , the 3rd string QB dont ever play, somethings happens he is called on to play. he helps out his team in this very limited play time/role and the team wins the super bowl he still gets a ring too.

Yes
