My problem with 3min buffs isn't that I don't know what is on who, it is that I am buffing again right as I stop doing 1 buff round. Three minutes isn't nearly enough. When people move around, I don't even bother buffing them, too. The buff range is so short that if they move just a little bit, it will tell me that they are out of range. The only way I could live with them is if they were three minutes long and group, or longer duration and more mana cost (or same, whatever =p) Also, they need to increase buff range to the same as "maintain" range.
