Warning: Large Wall of Text which should probably be a stand alone thread.
Disarmed itself is an annoying part of combat as seriously, 3 hits with someone with 1000 unarmed and your weapon is effectively gone. It is annoying, useless, and the only reason real hardcore PVPers train it is to get rid of this annoying ability. In my opinion iron grip should be buffed as someone that is 1/10 the skill of another person in hand to hand combat wielding a weapon with skill, should still be able to hold onto that weapon, even if outclassed in pure fist vs fist. Disarming should be useful against those that have under lets say 400 skill and ineffective to the point of near uselessness to anyone above.
"But I've watched Teenage Mutant Turtles at least 2 times and play mortal combat, and those quality sources prove that in real combat a quick punch or poke is twice as good as machine gun, let alone at least 50 times better than a sword."-Every pro-unarmed quasi "historian" ever.
Well I hate to break this to you, but a good sword in real medieval combat outclassed every single weapon in medieval combat (Disclaimer below) especially a bare hand, which if you look at very closely may be the reason we use weapons instead of our bare hands in war. Using your bare hands in a fight in the stone ages was suicide. Let alone the late medieval ages with the advent of bows, crossbows, metal, shields, tactics, large battles, ranks, swords, knifes, organization, horses, logistics, war dogs, ships, catapults, scorpions, trebuchets, cannons, elite units, cannon fodder, arquebuses, pole arms, mercenaries, advanced deception, military alliances, formation, flails, and those small unimportant things.
While I agree that PVP is not at all like medieval combat this wall of text has shown that any attempt to say it is RP friendly is simply false and it takes away from the fun of PVP. The two uses of unarmed skill in my opinion should be.
1. If your faction is poor and resisting much better equip attackers, you can train unarmed to fight them with a damage boost. This is not only leveling playing fields slightly but also is quite similar to a desperate last stand with conscripts using any thing from pitch forks to pots to a large spoon to defend themselves.
2. Using against people that have low unarmed. If disarmed was nerfed and made so it caps at perhaps 25% skill at level 500 and iron grip capped at 100% at 500, this would mean it would still have a low chance for noobs to disarm and a large chance for PVPers to use to their advantage against people they can't bother with while still not corrupting "higher level" PVP.
(Overall, no doubt 1000 Welsh Longbow men could annihilate twice their number of better armed, trained, rested french soldiers with swords in certain types of battles as proven many times before, but that is a certain type of battle not all battles the sword was better overall as a weapon.)
