I have a level 38 DRK, and I have full Calvary Set with HQ crafted Weapon, Pants, and all right side VIT accessories - yet I still seem to be quite squishy even when rotating all my cooldowns (-20% Damage, 20% Parry Increase, +Healing Received, Bloodbath, etc..)

Keeping both Grit and the Darkside up. What am I doing wrong? Is my level 32 gear already so bad?
