Meh, he's already proven that he will not be convinced that at will attack granting is possible to balance, never minding at will action granting. He hasn't even bothered to show why he believes this, only that he absolutely believes it and cannot be convinced otherwise.
There will always be people like that. They aren't the ones you have to convince because, no matter what you do, unless you 100% accept their ideas, they will never, ever actually engage in anything constructive.
Folks who could care less don't need to be convinced of anything.
I have seen at will action granting in action twice. Both times the player rolled a new character once because the party composition did not support it the second time because it supported it to well and the class used (Noble) was to weak at healing and gave up to much to enable it leading it to have to much variance. Note I do not think the noble is good design.
The basic argument against at will action granting in 5E is that it is twice or 3 times as strong as a major front loaded class feature that is short rest based and it is also a great class feature as well.
Its also basic math for a support class and you can compare how much damage it does v a cleric, Druid or Bards attacks.
I have said it about 50 times people don't want to admit it but its a busted ability in 5E de to the existence of the Rogue if nothing else and its a problem with a few other classes as well.
When people are comparing to daily powers on 5th-10 level PCs that may give you an idea of how silly an idea it is. I eman when you ay "But a sorcer can do it" they can but its magical, daily, limited, interuptable and with a big draw back if it is interrupted.
I mean all you want is a 150% strength level 3 ability made at will that compares to higher level spellcasters using daily resources that is perfectly reasonable (sarcasm BTW).
Go and ask Mearls on twitter point blank about WL as an independent class with at will action granting see what he says.
