I think the solution is simple.

If SE wants Tanks to max DPS they need to take away the penalty for doing so.

This is just like how they changed DPS for Healer. They obviously wanted the healer to DPS too so they took away the penalty. It seems they are taking into account DPS from all players in the raid/party when they are making new content so they need to change the abilities to coincide with that. The fact that they are not just shows negligence on their part; ether on the dungeon creation side of the players skill tools side.

The only reason why this is not a "Healer DPS Harassment Thread" is because it was resolved. Time to revamp the Tank DPS now.
