Guild Wars 2

Not sure if this has been asked before, but i would like to know.

For retaliation does not work if the move is blocked or it misses…
It counts per hit (a big attack will tick 1 retaliation)…
Damage depends on Power, not incoming damage, which is counter-intuitive to the description…
Supposedly it is called out for being OP since you can return damage from conditions, and considering the damage is relatively weak and your power is pretty good, then you are returning more than you are receiving…
There is a general consensus that its pretty useless if you go up against burst damagers.

Whats your question exactly?

When the boon Retaliation is active, does it reflect dmg when you BLOCK an attack?
Or only when the damage comes trough, and you actually lose a bit of life.

It seems the general rule for powers, abilities or whatever is:
Whichever is weakest, that’s what it does.

Retaliation does not reflect damage when you block or the enemy misses.

Thanks for answering my question. The last 2 answers were bright clear.
