Then again, I've only gotten the belt last week and haven't had the chance to play with it in Mythics yet, which might have a large impact on RT usage. (My base setup is actually legs + bracers atm)
For our recent Elisande HC kill, I've also swapped to High Tide & AG (running Floodwaters, QA & TC relics) for the more consistent AoE healing, where QA was up a LOT (63% uptime) and the combined mana save/return of bracers + Resurgence was 1.45mil mana (AKA 130% of my mana bar)
Floodwaters + QA for raid healing certainly is a strong combo, but I'ld say with the base 3 points in Floodwaters + crit from gear, I'ld advocate more QA, BW and TC or PotS as a middle ground for those doing both raiding and mythics, as you can't swap relics as easily as talents.
PS: On an unrelated note, AG turned out to be as efficient as Ascendance for me, with an average 6% overhealing vs the nearly 50% Ascendance usually hits. 10s/2min vs 15s/3min means equal uptime overall on top of not being the same CD as our 2 other ones, but not having Crashing Waves does make me sad. If only I could swap Echo or Vigor/Shield Totem for a chance to pick it back up.
