Also you have a low hp and its not to safe to be in the front
Aside from AoE you shouldn't be getting hit so HP shouldn't be an issue unless you are a tank. As a taru PLD, max HP matters very little because you have so much MP to help compensate by not only curing yourself to cover the HP but generating more hate by doing so.

and your strength isnt that grand either
Perhaps the biggest downside to taru melee, though our RSE makes up for this pretty well. However, the difference is pretty miniscule really and sometimes can be beneficial. Instead of being a melee that continually steps over the hate line and getting wtfpwn'd you can much more easily maintain a good DoT without causing the mob to turn and eat your face.
