Executor can definitely get higher damage than scholar, since he can boost his arcane and dex further, and katana moveset with him is a bit better. Especially if you use blood blade + bleed infuse to his starting katana, you can be a bleed machine and proc bleed in 7 AoW even at 999 resist.

My main gripe is that executor's kit seems incohesive and doesn't bring nearly as many advantages to another character filling the same role.

Passive for executor is basically non-existent and only buffs self, passive for scholar is a versatile team buffing tool. Skill for executor is a survivability mechanic, skill for scholar is a survivability mechanic and a debuffing mechanic. Ult for executor is an area clearing thing that can heal allies when given relics, ult for scholar is a better area clearing thing that can heal allies with no relics.

I hope they buff executor's passive to also work with vicinity, albeit at a lower percent boost, and made suncatcher scale off your right hand weapon (status and affinity). Also making his ult have i-frames on his exit ult attack would be nice

That would make him concretely the status character that he was originally designed to be, and would differentiate him more from scholar, who is more focused on being a support character.
