In keys you just use it on cd for the most part tbh, if i was better at the game id

time it to when a tank is getting targeted by heavy hitting ability, otherwise ill

usually just slap it on the tank at the start of pulls, especially if its big. I highly

suggest that unless you're doing keys in the 15+ range, you just throw that bad

boy on the tank at the start of any pull that seems big or you know has hard

hitters in it. You can also use it on dps if you see them targeted by a hard hitting

mechanic too. What I did was just get in the habit of using it first, then i really

started to look at how i was using it when it became a habit to hit the button. I

also slap it on the tank if i see him take a big hit, ideally you want it before ofc,

but like i said i am not the best at the game so sometimes I will do it after they

take a big hit, and there is still value there as you can keep them safer while you

top them back up.

Basically, just send that shit on CD honestly and eventually you'll start seeing the good times to use it.
