I can run without one." The stats on one piece of gear alone wouldn't make a substantial difference, but taken as a whole they add up and that matters.
An additional effective 3% effective reduction in damage taken does pay dividends, esp in pve where incoming damage is relatively flat. Burst damage, like the kind you face in pvp, renders the extra heal from RS practically worthless BUT the fact that HST can heal two targets with RS is not worthless.
