Guild Wars 2

I feel like this skill is borderline useless for several reasons:
1. it’s better to use the water autoattack, which has a better chance of triggering fresh air.
2. low damage doesn’t match it’s ease of use.

my idea:
1st. increase CD significantly.
then:
-ice field?
or
-blast finisher?
or
-damage buff?
or
-chill?
or
-boon rip?

thoughts?

Blast finisher makes the most sense imo. May need a longer cooldown though.

I feel that the current skill is okay in concept but is way too slow in its casting.

If I were to rework the skill it would be similar to the current one in terms of looks but would have 3 explosions each with their own damage values and effects, with the first one being the weakest and the last explosion being the strongest to reward good skill positioning.

Shatterstone:
Cast time: 0.25 sec
Cooldown: 12 seconds
1st explosion: Light damage, 2 stacks vulnerability
(0.5 sec delay)
2nd explosion: Medium damage, 3 sec chill
(0.5 sec delay)
3rd explosion: Heavy damage, 3 stacks vulnerability, 3 stacks bleeding
