The need for Agility buffs is growing day by day......as the need for high agility is now needed for the ever popualer Senpai line of armour (especialy coats). There are numerous stackable buffs for strength and stamina, but only one (non-general) for agility (to my knowledge) which is feline grace. Which in its self is not that great and agents have it? Why agents......hmmm......I would understand Martial artists or adventurers, but agents.......I think they have quite enogh to keep themselves well off.....without having the only agility buff.
Personally I feel Agility buffs best belong to MAs.....but that it would give a already powerfull class even more power!
Therefor I feel that Adventurers are the best class to recieve agility buffs, as they are in need of something that other class would depend on them for.
