I dont know. My company has now 3 raid groups and in every group we lack DPS and have to search hours before ro fill up the space with randoms. At the same time we have 4 Paladins hoping they can raid with the company if a maintank drops out somhow.

My experience is: while the duty finder the DDs have to wait quite long while as a tank you almost get instant invites, at raid stage it turns and you can find lots of tanks but are on a short supply on DDs.
