We played a 3E campaign up to the point where the characters were 13th to 15th level, and we did see the overpowering effects of haste, holy word, and some other spells. We struggled with 5-foot adjustments made by creatures 10 feet wide and 30 feet long (does swinging the back end around count as more than a 5-foot adjustment?). We wondered why sorcerers would ever use metamagic feats, etc etc. You get my drift. Anyway, 3.5 clarified a lot of the issues that bothered us.
