OK I dont get this... Knight are tankers and Warriors are DD but how come my knight is level 36 and friend's warriors is36 also but he has like 200 hp more than i do! What is going on here? I thought knight suppose to have more hp!
Simply put, Knights take LESS damage. Shield Block + other skills mean that even if a Warrior has more HP it only means that he can take a few more hits before he dies...whereas a Knight can take alot more hits and still not die.
And if that Warrior goes Warlord, he's gonna need all the HP he can get when he fighting more multiple mobs at once.
Granted, most knights really don't see the big defense/shield skills until after L40, but that is the reason.
For example, an Orc Destroyer has an absolute ton of HP comparatively, but significantly less 'tanking' ability under most circumstances. (VR and Good equip means they have can reach near the same survivability, but they lack in other areas that knights don't.)
Plus knights get 'hate' skills and warriors don't. (A warlords Provoke skill is slightly different and not really a 'hate' skill.)
