Boneshatter punishing for too much stun build up?

I really like the design and feel of the skill. However, since it doesn't build up stun itself, while using a second skill for stun build up, if the skill heavy stuns, jumping over primed for stun window, you can not proc the Boneshatter AOE.

This means in effect, you get punished for stunning too much, and having heavy stunned the enemies can actually be an impediment, which seems like a slight design flaw. My suggestion is, that maybe the Boneshatter AOE should also proc on hitting heavy stunned enemies.

I'm only testing out the skill in the early campaign, so I do not have extensive knowledge of how it works in mapping or on any builds, but I think it could use some tinkering. The rest of the skill is great, probably my favourite skill to use so far.

If anyone else who has more extensive knowledge of using the skill knows more about why this is or isn't something that should be changes, I would be interested to know.

there is a support gem that stop tun build up to reach 100% (not heavy stunned enemy)

I see thanks, that would explain it somewhat.

I assume you are talking about brink. I still think this should be unnecessary. I suppose they think it is too powerful otherwise? Sounds like it will solve what I'm asking about anyway. I'll give it a try, thanks for the suggestion.
