Props, %LP, and Reflect Caps
Now i believe a big part of why pvp is so imbalanced, is because of the insane amount of these stats a class like SK or Ultimate majin can stack combined with their high health, good defenses, and very powerful skills. Tell me, how is anyone going to kill an Ultimate majin with 12+ gear, 22k Lp, 67 props( 18+10+(13*3), 60% LP recovery, his insane amount of resistance, good heals, the ability to cure debuffs,bleeds,posion,abdominal damage, hyper-bomb which can reduce phy dmg by 40%, and the ability to get out of stuns? Its going to be near impossible to bring him down, not to mention his damage is decent as well so have fun trying to fight a nearly invincible player.

Now ultimate majin himself isn't broken, its just the stats that he stacks do not have a cap which can lead to this ridiculous raid boss of a monster that almost no one can kill. So instead of nerfing a class that doesn't require a heavy amount of nerfs I believe that Props should be capped to 26 on accessories ( similar to how % resist is capped at 60% on accessories for balance as well), reflect is capped to 20% on gear/accessories ( Dragon clan and Wonder majins have skills that grant them % reflect so I do not want to nerf these classes that do not deserve a nerf, so it is better to just cap it on armour/accessories again like % resist), and the %LP cap is reduced to 45% LP. The new %LP cap will also make chef not as undesirable anymore, and probably more wanted by tanks for their offensive buffs and increase in health and p def. Anticrit was already capped which was a step in the right direction, but now you just have to follow through on this.
These changes will make fighters and other dps have a much more fair chance at defeating these two powerful classes, and we do not have to severely nerf those classes either. Its a win win for everyone.
