With Warrior being so squishy..

[Galgarion]

Pffff, that's because pallies hide (cower) behind their shields. They block magic and physical attacks, so their incoming damage is predictable and smooth. Warriors mitigate through higher health pools, so it seems to spike more because they ARE eating more unmitigated damage, but we spring back like it's nothing thanks to our healing bonuses. Our flesh is the thickest, yum-yum.

Sounds to me like you're just experiencing dissonance between the two playstyles. The solution is just to pick one job over the other.
