Potential Skills Post-Big Bang

Yes you have too. See this is how it works, GMS (though I'm not sure if KMS fixed it, although there WAS a skill reset upon the bb patch) installed a different engine obviously than KMS. When you use a "decent" skill, the equip has to be equipped. You can't change it with another piece of the same equipment, so you have to trick the game, while removing the item. When you equip a glove or shoe, you can't equip something that forces it off. The game recogonizes basic concepts such as replacing and removing, but when it's forced removed, through means such as equiping an overall or a two hand sword forcing a shield to be removed, it's not a concept that game recongonizes and doesn't take off the skill.

Though I'm no programmer and I could be completely false, but that's the sense I have pulled from the methods to loophole around it.
