Combo finisher could have different tiers of strength. This would make balancing skills more easy because you can greater control how much of a buff adding a finisher will be. Some finishers have weak effects due to more spammable skills being available. This leaves some skills like tornado, kill shot, arcane blast or crippling throw to be weak finishers.
What would finisher tier affect?
Projectile: Affects strength of the finisher (amount of healing, or condition/boon duration or stacks)
Blast- Either strength or effect of area radius
Whirl- strength and/or how rapidly bolts are thrown out
leap- strength
I’m thinking either weak, normal, strong, or just normal and strong.
