aion Gohan
First of all, I want to give a little praise to Blizz for the addition of the dungeon finder. It has definitely made building groups extremely easy. Most importantly, I spend most of my time in dungeons now rather than waiting to build groups. So why is there going to be a problem upon the release of cat? It is quite apparent that there is a pretty big tank shortage already and this is only going to become more of an issue when the expansion is released.
Even aion gold posters on this board recommend that DPS to gear up and learn the instances and then switch to aion gold tanking. Otherwise you risk being repeatedly ridiculed and harassed, and generally just frustrated with tanking. Worse yet, when DPS are actually placed in a group they are likely going to have unrealistic expectations of instancing. The dungeon finder works great now because pretty much every tank over gears all of the instances. aion gold players are going to be when tanks are still learning the pulls and bosses, and wipes rather than victories become the norm? When instances are back to hour rather than 15 minutes.
