Heal not going off properly

[Caiahar]

Ive been noticing a problem in pvp alot. Sometimes when I use heal, it doesn't go off. I use it, the cooldown starts, but I never get my health. Even when im not stunned, it doesnt work. This is what happens:
1. Warrior uses skyward smash. I get stunned
2. I use fireball at the same time, causing him to be stunned as well.
3. I use lifegiver
4. Cooldown starts, but I never get the health, even when I recovered from stun and the warrior wasnt attacking
5. Warrior uses sky mill (skyward smash and windmill) and I die.
Countless times I have died because of this. Now that I have more deaths than kills, ppl assume im bad. When I explain that heal doesnt work, they laugh it off.
Can you fix this? Its becoming very annoying.

Same problem with rogue health packs, I drop them but they apparently invisible. So I end up without health :)

Healing sometimes not working cause of lag. Same with VB, SS, dunno why.
Ofc when they stun u just after releasing charged skill, it wont work too, dunno why. Bug? Or intended maybe, dunno?

I have 100 ping. No lag. No stun. It just doesnt go off

BAMP. Heal still not going off. It goes off, I see the effects, but it doesnt heal me. Even when im outside of a fight
