Question: Does anyone enjoy the idea of a debuff spell anyway?

Doesn't this seem kind of silly?:
"I wanna shield this guy so we have an advantage *buffs ally*"
"No! I don't want you to have that advantage *antibuffs enemy*"
"No but I want him to have the shield.. *rebuffs ally*" etc?

(In other words, maybe a good way to balance it would be to remove it?)
