Will definitely be useful on some mythics with not-so-obvious activation visual effects (Sanctuary) plus some others as well.
Well once you use sanctuary, you get a blue text with “sanctuary” but i agree it would be nice to see a graphical effect like a resurection in many RPG (FFIX etc) 
Ah, maybe I missed that because I have Damage numbers off, but yeah vfx will be nice. I think the miraculous process of death-to-life can’t remain bland forever 
Also some sort of visual effects, or the absence thereof, when Sanctuary is recharging… that’ll be nice!
Personally I am not aware of the other Mythics’ mechanics but pleease consider them as well, if applicable.
Synergy certainly needs something to show when the buff is on.
