The Frenzy skill of the Druid in Path of Exile 2 is absolutely terrible

Even with sufficient Fury, this skill will randomly stop channeling—it might halt upon contact with enemies, get interrupted by terrain, or even cut out occasionally when channeling on flat ground. More often than not, I end up stuck right in the middle of a pack of monsters once it stops. On top of that, the skill has an extremely long wind-up time, during which I’m vulnerable to being interrupted by enemies. And since the Druid’s transformed form is so massive, rolling can’t get me out of being surrounded. This means that if I stop channeling while in the thick of monsters, death is guaranteed. I really don’t understand what the design intention behind this skill is supposed to be.
