My quick and dirty read leads me to believe the war cleric changes roles as experience is gained.
At low levels it works as a great frontline warrior. Nice defense, good weapons, the ability to basically guarantee a hit when you really need it, strong spell support. That is quite a package for a strong soldier.
As higher levels hit, you turn from a soldier to a general. Can still lay down some beating but are probably better off making sure the engagement happens how you want it to, ensuring allies get the hits they need, making them tougher and stronger and keeping them in the fight.
A low-level War cleric is all about the fight, the high-level war cleric is about the war.
