MCMMO/Enchants

theres this think idk if its a mod or a plugin idk but basically its like skill levels and like when ur mining your skill level gets higher and u mine faster as it gets higher then u end up like when you use silk touch u get double the ore and excavating when your skill level gets higher u end up mining glow stone out of the dirt and diamonds out of the dirt and also it adds things like super breaker when u right click the pick and tree feller when u right click the axe and giga driller for shovel and ect ect anyways thats a cool thing to do

also theres this plugin it adds knowledge enchantment basically u get iron put it in a cross shape and add a diamond in the middle and right click the diamond with a sword or chest plate and it adds knowledge enchant and what it does is when u have the knowledge enchanted sword and armor u get triple the xp when killing mobs

feed back is appreciated

 

We used to have MCMMO before the reset and i was great supporter for MCMMO until maybe a year ago, but:

Super Breaker has never been allowed on our server and its almost only use was for mining obsidian. Vanilla combination of Haste II effect from Beacon and Efficiency V enchant on diamond pickaxe breaks obsidian in a split second and all other blocks instantly, so SuperBreaker ability is unnecessary.
Blast Mining would be useless because use of TNT is forbidden.
Demolition Expert would be useless because use of TNT is forbidden.
Double drop has been made obsolete by Fortune enchant (remember that MCMMO is older than vanilla enchanting).
Giga Drill Breaker has never been allowed on our server and it only "temporarily adds 5 levels of the Efficiency Enchant" as said on MCMMO Wiki - so why dont you just buy some Eff5 shovel?
Treasure Hunt has been allowed and mostly (ab)used to collect glowstone, so the ability was removed when we used to have MCMMO and it would be removed again.
Green Thumb has been allowed and i would like to have ability to instantly replant all crops, but as we had the Power Level capped at 200, offering just 13% chance for instant replant, it was close to useless.
Shroom Thumb - who needs mycellium anyways?
Farmer's Diet - restoring more hunger is useful but as you need to keep your food bar close to full to regenerate health, this ability wouldnt help much.
Hylian Luck (special drops of melons, pumpkin seeds, cocoa) - do we really need this when everyone can buy them from others?
Tree Feller - could be useful but would be forbidden.
Leaf Blower - instant breaking leaves? just use shears, there is plenty of cheap iron on the market.
Treasure Fishing - made obsolete by vanilla with Luck of The Sea enchant.
Master Angler - made obsolete by vanilla with Lure enchant.

And i could go on...
Conclusion = many of MCMMO features have been made obsolete by vanilla minecraft and other more useful features would be not allowed because they could be easily abused.
