Honestly ,to be quite frankly is to be better off inviting your friends list to play in foursome rather than hosting a game that when a certain player has issues .There you won't have to wait till they get into a game lately it has been an issue with loading ,pending on what browser they are using may have some issues .Like for example (Google Chrome) is a MAJOR problem in the past .
So, with that WGT staff can't really do much of any ? IMHO. As far for PLAYERS that who rejects , its on them they feel when by seeing who has issues they'll reject of joining in based on an individual player tier level if you ask me.
The best is to IMO take for what its worth and NOT be worry bout it ,just enjoy the game.
