Since 1.9 made different tools have different attacks speeds, I suggest changing some things if you do chose mcmmo. Make unarmed(if you use it) deal less damage, like at max 4 damage due to the hit rate. Make it so that each hit of the axe breaks more armor, but only works on full charge( like 2-5 more). Thats all I can think of for mcmmo. P.S not saying to add mcmmo.
