I run a travel intensive 3.0 game converting now to 3.5. Encounters are often spread out. In 3.0, the animal buffs (Bull's Strength, etc) worked for ever. Now in 3.5, they last only 1 minute/level. 1 minute/level works for an entire dungeon with short distances between locations, but outdoors, 1 minute/level might as well be 1 rd/level (after about 5th level).
So I'm thinking of house ruling animal buffs to 10 minutes/level. Still shorter than 3.0. Hard to have these up all day unless you really want to dedicate slots to them, and it makes extending these spells attractive again (one character has taken 3.0 extend spell for animal buffs and greater magic weapon).
Any hidden consequences I should keep in mind.
