Ressurect

All knows that WoW have more places where you always "in combat" and cant rez others ppl. (Like Onyxia, or Ragnaros fight) But if u die( if ur class are priest, pally, shaman) and you have ss, or someone rez u with battle rez, dont stand up fast. Before it just make a target person, whom u want to rezz. Click "Yes" and fast click ressurect ur target, and it works always

Well if you ankh as a Shaman you usually dont have enough mana to ress someone...

Only if you got some really nice Equip since you ress with 20% health/mana of your max.

aren't you always out of combat if you use SS ?

No, there are Zones where you are forced to combat, even after SS / Ankh.

Like Onyxia's Lair if you already attacked her. You will even be in Combat if you run into her Lair after you died and stand before the Instance Exit. ;)

every boss in bwl puts you in combat now after 3-4 seconds.
