We never had any problems in our games with spellcasters of any type.
A few reasons why.
1: Wizards- Spell shops weren't around every corner and random spellbooks were few and far between. You were mostly stuck with your 2 spells per level.
2: Druids- We didn't have any problems with druids because of this. The form chosen must be that of an animal the druid is familiar with. For example, a druid who has never been outside a temperate forest could not become a polar bear. Our DM actually enforced this so there was no flipping through the Monster Manuals to find the most powerful creature to Wild Shape in to.
3: Cleric- Nightsticks had to be approved of by the DM and if they were then you were only allowed to use 1. Also, if you burned all of your Turn Undead to power yourself up we were usually hit with tons of undead followed by a caster who specialized in Dispel Magic. We also found that even after those buffs the cleric couldn't out do the fighter because of the sheer number of bonus feats that the fighter got.
Anything outside of core had to be approved by the DM.
