It's a Feat Tax.
I think it is demoralizing to my players to only have a 50% chance to hit an opponent. 70% seems like a much better chance to hit. I've seen far too many players have poor dice rolls and basically sit out entire encounters. Certainly the odds indicate that it will all even out in the long run but those sessions where you miss every single daily are remembered a lot more vividly than those encounters where you hit every single daily.
The least fun way to play is not getting to play at all.
