It's time to return the ability to skill up back into events.
Currently, one of my biggest tasks in the game is to skill-up. Although, some of the skill-up rates are already abysmal, it would be nice if there at least existed a chance of getting a skill-up doing something other than standing around casting magic on myself, letting mobs beat on me over and over for defensive skills, or using two handed-weapons on EP mobs in Abyssea.
I'm not sure why it seems beyond S/E to have things like Twisted Roots and Fortifications NOT give skill-ups, but to allow the mobs to give skill-ups at their appropriate levels.
