As title suggests,

SE please consider changing the match up for Titan to allow for more DPS or Healers, as opposed to a second tank, the extra Tank (unless it's a geared Warrior) really does hurt the group, and the fight is hard enough for some players to dodge.

Also on my server Tanks for some reason are extremely popular so trying to Shout it is not really getting anywhere and FC's don't appear to be recruiting tanks. (Which is what you were trying to avoid by having 2 Tanks in DF right?)

Alternative: Select a Random Tank that queue's 1 of 2 and add a significant damage buff for Duty Finder, at the cost of aggro loss? Or just buff a tank's ability to deal damage in certain stances. (IE a Temporary buff that is applied to one of the tanks increasing their damage output by 30% of their Armor to keep the game fair -as in reward those tanks who spent the time to gear, just as you would reward healers etc for it)

I don't want to see the game be easier, but the current incarnation of DF for Titan is purely based on luck at the moment and from my point of view next to impossible.
