Problem with Zane’s skill

Finally got the skill changes to apply yesterday on Epic. But I notice some serious problems with the new active skill and duct tape mod.

There is a serious game breaking bug with the canon such that if you spam it too much, it becomes unusable whatsoever. Even if you aim it directly at the enemy the skill just would not trigger when you activate it. Crouching sometimes help but not always.

Also, duct tape mod does not always grant you immunity to self damage. I’m not sure how this skill is suppose to work anymore. The patch note says it grants Zane immunity to damage from your own guns and grenades. But I can still kill myself with Soulrender’s ghost. So maybe I misunderstood something or they just didn’t explain this skill at all.

Would you mind linking your bug observation to this thread?
