I did a quick solo test against multiple monsters all at once. This may not come to a surprise to most, but my conclusion was that Warrior simply out match Paladin when it comes to survivability when
fighting multiple enemies.
Here is the details on PLD, while fighting multiple enemies my MP was quickly being dried up, and I ended up getting KO'd in the end with only taking out a few enemies. The good; I took less damage compared to Warrior. The bad; lack of MP even with Outmaneuver caused me to die.
On Warrior, with Rampage and Bloodbath I don't have to worry at all, and for extra security I have Second Wind. Basically I was constantly recovering HP with weapon skills, and with the occasional critical hits. The damage I sustained by enemies is almost comparable with Paladin.
So, not a big difference here. PLD is heavily depended on MP.
For me this just proves
WAR is better against multiple enemies, and with more enemies the better my chances of a critical hit to recover my HP. I also provided a video, and before you laugh and nitpick at it I was lagging like hell while recording so I messed up a few actions.
If anyone gets a different result than mine please share.
