The skill has actually alot of uses, burst damage by itself doesn't seem to be one of them.
It gives you the ability to follow enemies through their escape, it lets you dodge key abilities by making you untargetable.
Additionally, it grants you healing in demon form or increases your follow up burst by resetting your passive in assassin form.
The ability is versatile, it shouldn't be a nuke by itself as well.

Remember that it doesn't work quite the way you expect -- it's not about burst damage, but mainly about resetting this (if you're in Blue form):
Whenever Kayn deals damage against enemy champions he also deals 12% - 44% (based on level) of post-mitigation damage as bonus magic damage, lasting for 3 seconds upon entering in combat with an enemy champion, refreshing after 8 seconds out of combat with them or by using Umbral Trespass.
So if you hit them, fight for 3 seconds, and ult, you get ANOTHER 3 seconds of up to 44% increased damage. That's huge -- the ult does have a lot of damage, but it's backloaded into give you three seconds of massive bonus damage.
If you're in Red form and build some AD, the ult also WRECKS tanky characters and gives you sustain to keep going, which is very powerful in its own right.
