Don't always select the same Kayne form. Make note of what players are chosen on each time before selecting Kayne's form.
Select Shadow Assassin if your team needs extra damage or if you need to eliminate a hyper carry in team fights.
Darkin Kayne has much more sustain, but can still deal plenty of damage. Choose the Darkin form if you need more sustain in fights.
You build blue essence (shadow) by attacking ranged champions and red essence (darkin) for damaging melee enemies.
