This build plays aggressively and in the face of the NPC’s, who you hit very hard (an average of 83K per bullet vs elites, the same as an AR based 8K firearms Striker with 40% DtE and 70% EAD with ~45 stacks built up). At 122K skill power the shield has ~780K health which I’ve found is enough for up to Challenging PvE, it only breaks if I’ve done something stupid. Keep your shield and any environmental objects between yourself and the NPC’s. Using the environment smartly can allow your shield to regen its health. You can also use a medkit to restore its health and yours if you’re in a bad situation. Nomad gives you some HoK which is enough to keep you alive and not need a healing skill. If Recovery Link goes off, swap to the secondary (sprint for a moment and swap in that moment, end the sprint) to get it back quickly with Determined then swap back. Use Booster shot for a DPS boost against heavies or bosses.
