To point 3:
I could have used my swift for a Shadow Flare or derped the raise (Swift goes off too late u don't notice you didn't actually raise).
I could think I don't need that deco healer that anyway only costs mana to raise and will derp all mechanics again.
Also consider even a Swiftcast raise costs me 1 GCD. Had A2 where shit went south 1 tank n other healer down I powerhealed it to end and barely dared to swap my hotbar for a sec to rouse my fairy. When I finally dared to swift/raise the fight was over.
