Skills for the hero!

Just finished playing a random map. I managed to recruit 75 Titans through diplomacy. In general, whether or not to take the diplomacy skill depends on the map you're playing. Logistics or pathfinding are absolutely necessary for any hero.

I also don't really like magic... Although you can level up some... But still, rarely...

So, you rarely level up any magic? Do you mean air, water, etc. magic?
