Single target makes it even more useless, as supports can only chose between themselves and their ally for mana restoration, and removing the fact that it's a percent makes it useless for the occassional player who would use it to complement Muramana, using it to keep their mana (and, by respect, damage) high.

This isn't a buff. This is a nerf.
