Rules-lawyering drama queen... Be nice plz n_n
Maybe you should check DAS or Talislantla. Just saying.The dice pool mechanic I'd advocate is roll a number of d20s based upon your skill ranks (and combat would be skill-based too). Roll under compared to your target number (skill value with conditional modifiers). The amount you succeed is a margin of success (and vice versa for failure). Additional successes add to your margin of success.
Armor would be solely damage reduction rather than the insipid "makes you harder to hit" in D&D.
Hit points would be used as injury thresholds, so you don't remain 100% effective down to 0 hp (with the added benefit of the player naturally knowing when it is time to run away rather than stubbornly staying until you have a TPK).
I like this type of mechanic because everything can be precalculated on your character sheet.
