I've long disliked the general weakness of Summon Nature's Ally, and I know I'm not the only one. Currently, the only real edge it has is that SNA gets the tiger, while Summon Monster, obscure AP issues aside, does not.
Are there any suggestions for buffing this spell's lists up a bit? A druid focused on summoning "friends from the forest" (rather than an Int- or Cha-based witch/summoner focused on summoning such things, thank you very much) could be fun to play.
