Looks like there's been another patch:
- Fixed the bug with enchantments staying on an enemy Great Mage upon his/her defeat.
- Dragon Farm now has the correct model.
- The attack of capital cities was improved - damage was increased, attack now have elemental magic damage, and becomes aoe from certain level of a city.
- The attack strength of defence towers was improved.
- The resistances of several units were slightly decreased.
- Appeared the option to switch off the intro movies.
From what I've noticed, the capital cities really hurt now, especially early on, and they also got range increased to 3.
