It doesn;t matter by who - the numbers were crunched, and statistically, it was fairly well shown (e.g. proven) that the benefit of a 2d6, 20x4 weapon was not much better than a 2d6, 19-20, x2 weapon. Certainly not worth a feat. I think they even compared it with Weapon Focus, and saw that that was better than MG.Carceri said:Statstically proven... LOL. By who?
And don't give me that crap about paying the extra feat. You gotta be kidding me.
And I can't believe you're dismissing the palpable cost of a feat to use it properly.
Just because you're using the one PC in your campaign as a comparison, doesn't mean that's how the feat should be defined by.
And what's abusive about this PC of yours, anyway?
He's got a 18-20 crit weapon, after taking Improved Crit:MG, and he can have an almost-guaranteed x4 crit, once per day with Power Critical, right?
You should see a Lance-wielding, Spiritied-Charge-using, Rhino-Hide-wearing horse-rider - he'd terrify your group, apparently, and send you curling up in fetal throes of "broken!" "Munchkin!" "he can do that on EVERY charge attack?"
