I'm not sure where else to put this, so I'll just post this blog :P
I have a few suggestions for new MCMMO skills:
Enchanting - You could get .01% more xp per orb for each enchating level you gain. There could also be an ability gained at a certain level that allows for enchanting without an enchantment table, maybe by right clicking with a book?
Brewing - The time it takes to brew potions could decrease by 1 second every 50 levels, then at level 1000 it would be no time. There could also be an ability that allowed you to brew potions without a brewing stand, maybe by right clicking with a blaze rod.
I hope you take these into consideration, thanks :)
