Warrior main here. I think we are the least popular due to the heavy responsibilities we have in dungeons. A tank's mistake is far more obvious compared to a DPS or healer slip up. There was a thread posted the other day showing how much abuse we get if we wipe, even if it isn't our fault simply because we're up in front. I did notice that there was a massive number of tanks farming FATEs in Coerthas, perhaps they don't want to actually do DF group content?

I myself love finding a friendly group in DF to play with, however those people you hear about raging how bad tanks are put off a large number of potential new tanks.

So if you want to make friends and get into dungeons quickly, pick up a tank class and learn to do it well. No point trying to tank if you aren't willing to try
