Skies Below

The current working title for my homebrew game is Skies Below. And of course, I've thought of a new combat system for it. My goal with designing a combat system is for it to be logical, simple, and dynamic.
This one includes three main attack options; press the attack, parry and counter, or feint and follow through. These work similar to rock-paper-scissors, except that while anyone can press, you can only parry with a weapon, and only combatants with training can feint. Additionally, anyone with a shield can block, increasing their defenses for the round.
If your attack beats your opponent's, you deal 1d6 damage modified by weapon type, plus strength modifier, and reduced by their defense. If you pick the same attack as your opponent's, you deal 1 damage plus your strength modifier, reduced by their defense.
Beasts and other unintelligent combatants can lunge (as press), or latch on (as parry), and typically cannot feint.
This system works well because the attack choice can essentially replace the attack roll, though it doesn't include provision for critical attacks. That's the main thing I want to consider in the future. For ranged combat, it's simply going to be a skill, either archery or throwing.
