I 2nd this, same situation here!!!They need to add solo ranked pvp.
I can't stand random battlegrounds full of people who don't care about winning or losing but I don't have the time to look for competitive partners either. When I log in for one hour in a day and want to do some pvp I end up looking for someone for an hour instead of actually playing.
Just add the ranked system the way it works in mobas, where you get matched with player with similar skill within minutes. I'm mostly doing arenas with random people from group finder anyway and I'm not the only one here.
This would also be an easy way to introduce more people into arenas and ranked bgs.
