Why do pyros have shield, mega heal, snare/root invulnerability, and defense buff?
Why do marauders have unbreakeble stealth, god mode, saber block, and long-term damage reduction?
Why do sorcs have immortal bubble, free heal, self bubble, bubble stuns, and knockback roots?
Why do gunslingers have cc immunity, team damage mitigation, a knockback root, and various other defensive procs?
Why do assassins have shroud, saber block, stacking damage mitigation, and a damage mitigation buff that can activate 4 times before cooldowns begin?
DPS operatives have only evasion (which lasts for only 4 seconds and protects against neither tech nor force).
Our roll ability? It's useless while snared/rooted.
We need a defensive ability/mechanic that can keep us up long enough to fight through the multitude of defensives everyone else has.
