if you add deserter on leave q it wont change anything, simply wait until the enemy premade joins then q after xD gotta love these people claiming things will get fixed without simply thinking for 2 secs at all the possibilities, this is how its been done since 2005, it wont change theirs always a work around, fix 1 thing break another. stop QQing, if you want to have fun as a solo player dont cry when you play against a premade, make your own premade and fight them.
Our devs have much better things to worry about then a bunch of anti group players that want to have "fun" knowing that they have the chance to play against one, refuse to form a team to fight them, then cry when they vs them xD THIS IS A MMO you dont do 5 man instances for pre raid bis solo, you dont get anywhere in pvp for the most part playing solo (unless it was pre nerf AV rofl), get used to it.
