I've never played SR before, but kinda want to try it now. My main is PT tank, his gear rating is rather low (236), I went for high-endurance build (Fortitude augs, Discipline enhancements, Leththal B mods, Bastion left side, DPS relics) and usually use tank stim. So I would like to get some advice to help me get into SR tanking, like should I gear differently (or not bother until I have better gear), how does it compare to unranked arenas, and so on. Any advice would be appreciated. Thanks!
