Well ijust came out of a Neverreap run that ran smoothy but had a twist at the end. Circumstances lead tome being the tank for the last boss over the actual tank and also me and the other lala in the run (the healer) 2 manning the boss and winning (props to said healer BTW).
It was fun but I'd think I'd rather be GNB or an actual ranged tank if I wanted to tank with a firearm going forward :P
