Hickory: That's only a problem for people used to min/max'ing. When you consider that her role is not pure druid, but a hybrid fighter backup character, her wisdom is perfectly fine: at 14 she still gets a bonus first level spell. For power players, I can see your point, but otherwise she's a great asset, character notwithstanding.
For someone roleplaying and sticking with characters who made sense to travel with from a narrative perspective like I did (Khalid, Imoen, Xzar, Montaron included), she was the only healer in the party, and her lack of bonus spells made itself felt hard. Granted, her low Wisdom doesn't hurt as much as it does in BG2, where she starts getting access to higher level spells that lack those bonus slots.
