You’ve made it sound like it is actually possible to have heal tanks like in TSW
Ofc. when there is party cleanse then no other heals are required. Self healing is pretty strong here to pull you through almost anything.
Speaking of HR6… as melee I kinda need cooperative tank there DPS req. are extreme, can’t afford to loose much by safe running around just because red or yellow circles are out. So while managing red circle I’m running from side to side of boss just outside the cleave. An unannounced movement could lead to no win situation (ofc. I’m aware tank’s circle and his need to go to well in time and moving accordingly).
But there are few things tanks can do to make the fight easier:
if U-turn is needed, there is always time to do one step in the direction, wait for 0.5sec and continue. Just like dancing you know. Letting others know the intentions. (It’s good habit to have, using it on other bosses.)
tanking boss in the corner/side is always dangerous. Circles will spawn, the need for quick turn happens, long way to well. If the boss is turned and moved away from corner/side before the next well spawns there is much more room for manipulation, evading (and showing tanks intentions)
the same comes with the center well. Moving boss slightly further helps determine and prepare for yellow phase (like not being killed by wrong DOT and having some space for managing red circle while inside yellows). Instead of just getting first yellow layer out of nowhere
