Guild Wars 2

Dear game developers,

should the guardian healing skill called “Shelter” be interrupted by unblockable attacks or by the users themselves, it always goes on a full recharge instead of only 5 seconds cooldown, which is usually the case. And of course you will not be healed.

Sincerely yours
Scion

Skills will go on the full cooldown when interrupted if you could have benefited from it in any way. In this case it is the block. Basically they don’t want people to have infinite blocks on a 4s cooldown.

The same can be seen on other skills such as Elementalist’s Meteor Shower. If cancelled before any meteors fall then it will have the short cooldown but as soon as a single meteor has fallen then it will go on the full cooldown.
