What mixed hero class (tactics) do you prefer?

I thought for a long time about which is better – a Crusader or a Guardian – and chose the Crusader. He is more practical – firstly, he can be created without leaving the city, and secondly, he can be easily turned into a Guardian (he summons a Satyr, it casts Morale – and again, you get a Crusader!). But this is in the Castle of Life – in other castles, it’s more difficult.
Warlord – both skills are passive, and he just swings wildly in battle. It’s a good class, but if you level up his active skill, the class will change.
