Pally Power is the key.
Please snag the latest version if you haven't already here:
http://wow.curse.com/downloads/details/3738/Our raids will go much smoother once all the buffs have been preset at the start. I am working on updating our "required raiding mods" and this will definitely be one of them. Thanks!
'eh', pally power is ok. Its only good if you are short paladins. If you bring 3+ paladins to a raid, most times it is set that Pally A does Kings, Pally B does Salv/Light, Pally C does Wis/Might. Then any extra fills in the spots. Buffing isn't hard if people listen and remember. I could manage 3/4 paladin buffs without pally power in the past.
Though I will say the hotkey system of the version of Pally power I have is absolute crap. it always resets some auto buff key to ',' no matter how many times I remove it.
