Guild Wars 2

People are still able to hit thief for a fair amount of time frame while one is Death Blossoming.
Anyone else noticing this?
This is the best seen when two thiefs death blossom each other at the same time, they will both take 1-2 or ticks while in the evading maneuver.
In team fights, while doing Death Blossom three times in a row, one still takes LOADS of dmg. Thief seems to be evading for like 70% of the air time and the rest 30% one is vulnerable.
A bug, or intended?

The ability does not have invulnerable frames for the entire animation.

Why would that be a bug?

TeoH.2098:

The ability does not have invulnerable frames for the entire animation.

Why would that be a bug?

Because, for example, rangers shortbow ability Quick Shot states the same in a tooltip, but doesn’t share this problem. Same with the basic endurance dodge.
