I've noticed there was a skill on the McMMO wiki that we do not have on our server, the alchemy skill. This skill should be added, as it allows you to create potions not available in minecraft, like haste, hunger, jump boost, health boost etc. Also decreases time to make potions by a alot if the skill is maxed out (Up to 4x less) http://mcmmo.wikia.com/wiki/Alchemy
I believe the latest version of mcmmo adds this along with fixing many bugs from 1.7 (I.e. xp values for new trees/fish). We'll see about updating it here soon. If the potion bonuses are too much, we can always disable them. Sent from the Sea
