Its actually insane how much value this skill has.
It's pretty close to a 7 second invuln on a 25s CD.
If you fight a thief and they drop this, you can literally do nothing.
Fight inside? Literally every one of you skills miss cause of UNBLOCKABLE blind pulses on a 1s interval.
Pressure from the outside? JK destroys projectiles.
Potentially even for your entire team, for those res and cleave situations ....cause a 480 diameter seems reasonable.
A CD increase won't cut it for this skill. Not even to 45s as the latest update suggested (https://en-forum.guildwars2.com/discussion/97627/balance-update-update-pvp)
