I should have clarified that I never had issue with damage output. It was the overall class features.The problem is that its always about damage.
Think about it. Why do people want to have concentrationless HM? The answer can be distilled down to damage.
If you break concentration on your HM for Lightning Arrow, you'll have to either continue the fight without HM or recast it. Either way, you're losing damage on the spell slot you used for HM. But if you take the actual opportunity costs, you're far more likely to benefit from Lightning Arrow at an instant than just keeping HM up.
The alternative to adding a core combat feature, why can’t you just use the example of the Paladin’s Improved Divine Smite. Take the subclass damage bonus at 3rd level that is applied once per turn and add an addendum that at 11th level you can apply said damage to each attack.
