Rules lawyering is bad; inept rules lawyering is even worse, and deliberately inept rules lawyering for powergaming purposes is... oh, just see my sig. I'm not about to try explaining Pact of the Blade RAW to anyone who doesn't actually want to understand it. That's a non-starter.
This isn't directed at you specifically, NaughtyTiger. But others participating in this "discussion" are doing so in bad faith and I consider engaging with them a waste of time.
