I want to be able to win going heavy magic, e.g. a powerful leader that can cast powerful spells during battle or how about summoning a army to fight for you.  What about zerging your foes to death, lots and lots of poorly equipped soldiers ready to die for the glory of the empire.  Maybe quality over quantity is more your style, a few very powerful units equipped with the best your kingdom can make and lead by the most experienced champions.  How about an army consisting of monsters, ogres, goblins and giants oh my.   This is what I'm hoping to get from FE.
