i was thinking about this most of the day and i don't really see the point of the Spine Attack. if u split up the abilities they go:
Warp Strike (Nuke, Chase)
Spline Attack (Nuke, Finisher)
Warp Area (solo finisher, AoE)
Shadow Swap (Excape, Gank)
so Spine Attack is the one move that already has roles filled by his other abilities. also none of his abilities have any support/buff (like heal or slow or something). my suggestions would be to replace Spline Attack with either something that slows (which IMO would make him imba) or maybe a targetable ability that increases Demigod Regen by say 200% or something. it can still be a Spike coming from his tail animation but this way its not so much another nuke in his arsonal but more a quick escape and heal tactical move.
this might also open up more builds for him like going Shadow Swap and Healing Spline (warping a UB into the middle of a few demigods then increasing his regen so he can survive and kill them all with ooze?) just saying... whats the point of all these nukes if he can't be a team player?
