Hmm, I was trying to find it but I can't now. So let's assume it's just 25%, even still, they do get an increased effect from vit, more than pld. And usually on Titan, a pld in there will have between 5-5.2k hp, and wars will generally have around 7k (at least from what I've seen). Nerfing paladin's defense is no different than buffing WAR.
Paladin's defensive mitigation is the only thing it has going for it. I'm sorry if you find the warrior playstyle stressful, but saying "hey, let's just make it so the class that was designed to take a hit, can't take a hit" is just ridiculous. a 4.5k mountain buster with a PLD tank would almost guarantee a wipe.
