It was a valid point way back then when GL's were introduced (especially for 3v3 and before Vader got his touch up and JKL was introduced). There's been enough time now for people to prepare. We know that the GAC algorithm is looking at the top 66 (3v3) / 80 (5v5) GP chars in div 1 (and fleets to some extent but details are unknown) so everyone should know that increasing the GP of that chars is going to affect matchmaking and result in getting matched with tougher opponents.
