Epic Meepo
Hero
Would it be more palatable if the subclass was all about turning into a plant creature as its main theme, and the extended reach was due to your arms becoming branch-like instead of your axe becoming branch-like?Elements bending or Plant like Groot would be OK.
It's the concept/visual of adding 10 feet, and making my Barbarian no longer swinging a righteous axe, but becoming a vine monster.
I do agree that the "roots of the World Tree shooting out of your weapon" thing is a weird visual. I think I'd like the subclass more if it was the Path of the Treant (or whatever) instead of the Path of the World Tree. Instead of having all these subclass features invoking shoe-horned World Tree imagery, you'd just slowly turn into Groot/Swamp Thing/Daphne from Greek mythology/[insert other plant-person here].
