Make it a dps chocobo with choco regen.
A dps chocobo is much better in the long run as once u settle in 50 you'll be too strong for those 50 mobs anyways.
Since you have topaz and soon to be titan egi you'll be set for tanks.
So the extra dps via your chocobo will help greatly when u need to solo content like when you do a boss fate and you are the only 1 there.
