This may have been said, but what if Improved Critical started at 18-20, and then increased to 17-20? (I'm not worrying about multiclassing in that thought.)
I'll test it, but here's the quick look at it.
A crit adds weapon damage die again. Best case scenario is 2d6* with rerolls, or 8.33. This is statistically similar to 9 from 2d8 from two maneuvers. At 15% crit chance, you'd need about 14 attacks before breaking even with the battle master's 4 superiority dice, not mentioning he utility of their attack modifiers. At level 5, that becomes far more doable.
I don't like it, though. It's bland and random. I'm personally thinking of giving them a to-hit and damage bonus.
