Actually, all in all, Bards are terrible buffers, spellwise. All their buffs are from performances.
Summoners are probably the best buffers. They tend to get all the buffs Sorc/Wiz get, and sometimes get them earlier. Haste's a level 2 spell for them, for example.
Dammit, staring at the spell list is making me want to swap out Kikuya's build for a sorc or Summoner. Need to stop that.
