You can stun non stop to protect your team, but you have no way to counter most of the time when enemies get close.
Mode 2 gives you rock boost and heavenly mobility, allowing you to play Sinanju like a rock suit. Not!Char kick reloads fairly fast, and the melee is superb even without the Ghost of the Red Comet skill (which gives a little boost to attack speed). The only downside is you only have zooks as a weapon, but the good part is that the projectile travels nearly as fast as a beam rifle shot but not as fast. It is best to learn to aim bazooka-type weapons before using the w2.
Also remember to decide to purge only if you don't see the room filled with units that have PS armour.
You do not want to fight a IJ or Meteor justice with purge mode Sinanju.
