Here's your problem, you're using Heteiros gear on a PLD. Heteiros has even less vitality than regular AF1, and peltast is even worse. If you're gonna do it with Andapor gear go with Hoplite, but running amdapor you can get by with mostly AF gear, although it isn't too easy. Beyond that you look fine, just don't try tanking Titan anytime soon (and to a lesser extent, Garuda) :P

TL;DR try to get tank-only gear, not DoW or DRG stuff.
