Which monster do you like the most in Heroes 5 (level 4)?

Nevertheless, you can create a pretty decent caster and surprise your opponent in a very unpleasant way, especially if they weren't expecting it! Of course, it's not as good as a Tier 3 Enchantress, but it's still not bad, and considering how quickly knowledge increases, plus the mana regeneration from education, there will definitely be more mana than a Tier 3 Enchantress has. IMHO, the upgrades are quite comparable, and Druids overall are one of the most useful 4th-level units.
