Uhm no, there are ways to get around such a limitation. It’s just that it requires a massive overhaul of the game in its core.
That would be a solo queue like every other game. It’s unheard of for a game with heroes and specs to lock you into only playing one thing before you’ve found a match, in a rated solo queue.
The problem with how the game locks you into playing only one thing is a problem for solo queue even Holinka acknowledged back in the day.
But you know, the ones who thinks simply adding solo queue would work like a dreamlike utopia don’t exactly understand the consequences of adding class/spec filters to a solo queue with the game locking you into only one character when you queue up.
