I have said this before and I will say it again, give WAR a passive that turns all their self heals into a shield if they end up over healing themselves, this will balance them out and also lower the skill cap required to play them properly. There is a huge skill gap between WAR and PLD which needs to be lowered. This alone will go a long ways into making them on par with PLD. After that, if its still not enough, then talk about doing other buffs with em.
