The Devs need to balance RDM similar to PLD.
If PLD use their progression tool he will suffer DPS loss, because he could be using on a Damage skill that costs the same MP. And PLD is the second best damage from the 4 tanks, less than GNB.

RDM could have a skill that costs the same MP as a Ress. That way RDM could be with a similar DPS with SMN, because if he uses his progression tool he will suffer a DPS loss, and will stay with the DPS similar to what he is now. I say not better than SMN because RDM still has the mobility.
