And true. Powerful Build didn't exist until...Volo's, maybe? I agree that it should be updated in D&DOne...though unfortunately the playtest didn't really indicate WotC was thinking of doing so, iirc.
I am kind'a hoping that once they have the big things ironed out they'll turn their eye on some of those side systems that need touching up. It's reasonable to think that if you can lift a guy over your head casually you can also throw them further than someone who can only drag them.
Every UA adds a couple more mechanics to revise. Seemingly completely random. So we'll see if they ever get to throwing stuff.
