The real problem is not a single one of you could be bothered to roll a lancer to try and fix the que problem you just complain.
I couldn't tank with my warrior endgame so I rolled a lancer, problem solved.
...and I still have the warrior down the road when they fix the problem.
or..... you could stop complaining and find on-server groups..
i have never had problems finding on-server groups to roll with, and through my time running dungeons while progressing through the game, i have developed a friends list FULL of people who love to run dungeons with me. to the point i have to remove people i dont see regularly to make room on my friend list (side note, 40 friends is a ridiculously small cap).... so not even at endgame yet, i have 40+ people (plus guildmates) who will run dungeons with me. more often than not, it takes maybe 5 minutes or less to organize an entire party from my friends list, 10 tops if i have to find a few pug players to fill in the gaps.
if you are a GOOD warrior tank, and do on-server groups, the people you run with will be willing to run with you in the future. the farther you progress, the more people will be on your list, and you will have no trouble at all finding groups for dungeons.
only reason i can see not to do this, is because you have to type and do more than just click the que button, and wait till it pops.... might be too much work for you, idk.
Don't get too excited about how wonderful a warrior tank you are. Most of us are willing to run with a warrior tank, since it beats doing no runs at all, not because we prefer warrior tanks. It also saves us from having to roll a tank ourselves.
