While your soveriegn is your avatar, the wars foiught in game are somewhat bland due to high level champions having no egos to turn events interesting,  It just makes the game intereswting if your champions let the egos inflate and their stupidity loses battles.  For example;

A prideful warrior will sit out a battle if nothing worth killing is present.

An envious mage may not work with another mage and if forced, suffer a large penalty.

Duels between champions, either allied or enemy,  from slights of honor.

Ambitious champions would stop at nothing until becoming your right hand,

Just a few ideas so that the game becomes intersting when your plans are thrown out in spite of your champions egos.
