So this is not a troll please don't take it as such. I'm a prot warrior and I invited a resto shaman, and a ret pally from my guild to que for some dungeons. Normally when I que solo as tank it's insant que. We qued for random dungeons and this is what we get:
I leave group after the SC and try queing solo. Insta que! WTF LOL so I decline, and get invited back by the shaman, we que again, and It's instant and we enjoy the dungeon.
Thought this was a funny little quirk, we got a good laugh out of it, just didn't make since that we needed 2 dps and we had waited for over 4 min lol.
EDIT: lol for some reason I said I was a prot PALLY, not warrior >.<
