Ok, so I was looking up things that are new in 1.4.6, and I came across this
http://www.minecraftwiki.net/wiki/Enchanted_BookIf you read closely, it shows that enchants now may be placed irregularly, which includes the ability to add sharpness, fire aspect, and all those nice sword enchants, onto axes. I raise this point because, with McMMO powering up axes, along with these enchants, axes will become OP, and crush the other McMMO melee stats. Knowing the admin team, I'm sure you already have, or are in the process of making, a solution for this once we upgrade to 1.4.6. I made this topic to raise awareness of the issue, and hopefully give us a head start on solving it.
