Why does everyone blame the tank?

[VallisRaine]

i had the same problem yesterday tanking on War. My Pld is 50 so i know what im doing or atleast i should xD. when we started our healer was a 33 cnj (no whm) her gear was passable the problem was she was a bot... spaming medica out of my range and then running up beside me to cast cure II.. we made it to the boss somehow losing protect because she only cast it once and didnt cast SS the whole dungeon. At boss we wiped after asking several times for ESUNA!!! 2 of us dieing with max poison stacks lol.

So the party vote dismissed her and her rep popped in lvl 34 cnj >< but he was a person and it was his first time there so i told him use esuna and avoid stuff and we beat it first try.

The Next run of bray we get a archer in a Cowl and Mnd earrings who half way into dungeon dings 37 w/o brd... he was terribad. i asked him nicely if he knew he was wearing mage gear and i got no reply.
Is this a new trend just not getting jobs?
