I actually never used stances, neither in the original game nor now on the EE. I consider them rather useless in general but sure, they should of course at least work the way they are intended.
Power stances were useful if you could minimize the chance of missing (through your attributes or doing something to the opponent that grants a guaranteed hit, e.g. knocked down) and you absolutely needed that opponent to die that turn. Toggle it on, land a heavier than normal hit, target dies, toggle it off.
With the toggle function being removed now I don't really like power stances that much.
Damn, that's awfully counter-intuitive. Using a +chance to hit stance with 100% chance to hit devices was stupid, but using a +damage stance with damaging skills is a... reasonnable thing, on paper.
Oh well...
It's not +chance to hit with 100% hit chance that was the problem (although you're right, that would be a stupid time to use a precision stance), it's the fact that skills/spells don't miss, and how it makes the 20% increased chance to miss penalty on power stances meaningless.
