Atleast he will not have to search for teamates for hours in order he get shit on later. With soloqueue he will just press 1 button and start playing the game, and maybe with this way he will have patience to play more than 5 games.
Atleast for me, the main reason I don't find the motivation to queue arena that often these days is not because I don't like the game, is because I don't have the patience to search 30 mins for partners in LFG so that someone rage quits after the first lost and i have to start searching in LFG all over again.
I want to press one button that will automatically do the search for me, like in every other PvP game.
Surely what you're really saying is you want an easier time to find partners.
Could just allow the queue system to filter via:
Achievements, e.g. 2k last season, 2k this expansion, 2.2, 2.4, 2.7, duelist,glad etc.
