If you're queuing for Wolves' Den, that's your first mistake.

Tanks in PvP are not damage dealers, so you're not meant to do that much damage, or even "tanks" in the traditional sense. You're annoying flies that stand in front of a healer and autoattack during every single cast until your team kills everyone else. That's your role. If you don't like it, don't roll tank in pvp because I think it's boring as hell.

My queue times for frontlines are always less than 5 minutes at peak hours, even solo queue. Frontlines queues do not take your job into account, so queue times are the same for all roles.

One on one duels is always something that people think they want, but once they have it, you'll realize that it's not interesting at all. Tankier classes will always win and all you do is mash out your non-positional combos until one guy is dead. Fun for like 5 minutes as you duel your friends as a dps test but then never do it again. Obviously there would be zero rewards for doing so since it could be so easily abused/boosted.
