As a guardian, I have some skills that might grant me retaliation, which is very good against burst classes.
The question is, if I "Block" (Aegis for example) an attack, will the other player still be dealt the damage that would have damaged me?
The wiki link says it does, but I'm not sure about it:
Retaliation does not reduce damage taken by the affected player, but damages anyone who hits them (even if the hit doesn't actually inflict damage; for example, if it is blocked).
