Unity of the Elements

Has anyone actually played as this hero? Maybe I'm just a bad player, but I couldn't achieve anything. I still don't understand how to remove the outpost in front of the castle. It's impossible to defeat the demon or necromancer. I completed some minor quests, but they didn't give me anything significant. I'm still stuck with just one titan (well, I can also use 15 djinns). In the library, there are 200 mummies with a speed of 7 and an initiative of 15 - that's a joke, and the same goes for the pyramid.
