The problem sometimes with MMORPGs and their PvP system is that over time certain players reach a very high skill level, but you won’t find a lot of them. Basically, that means that they will either have to wait an eternity in the queue in order to find a fitting match, or they will get matched up against less-skilled players that then get absolutely crushed. Both of these situations are quite obnoxious for everyone, so Guild Wars 2 developers decided to remove the duo queue option for legendary players in Season 9.
Season 9 should be arriving in Guild Wars 2 fairly soon, and when it comes, this change will get applied. Now, everyone except the legendary players won’t get affected by this change, but for all of those legendary players, this will affect them no matter how you look at it. Of course, there aren’t many legendary players in the game, even the developers said that they are a “tiny fraction of the player base”, but that doesn’t change the fact that you won’t be able to play with your buddy if you’re both legendary players. But, considering that this will overall improve the matchmaking at the higher skill levels, it is a much-needed change.
The developers didn’t remove duo queue for everyone, which some players might find strange, but it was the correct thing to do since the problem only exists with legendary players as they are so few and far between. Of course, if this change causes any problems or if it ends up being unnecessary, it can be adjusted or revoked without any problems, and the people over at ArenaNet will be keeping a close eye on Season 9 and how this change affects the players and matchmaking in general.
Judging from the comments on this post, players seem to be genuinely happy with this change, but we will have to wait and see what they will say once Season 9 goes live.
