Pros
1. Stun is a great mechanic for survaivability. Over 90% enemies just can get me because we can stunlock them. Also, we can ignore scary mods on bosses because they also can't touch us (except unwavering ones);
2. Cheap boss killer and map cleaner because we use sunder too;
3. Great party safer. Don't care about group because srun mechanic avoid them
4. That's funny! Yeah
Cons
1. With unwavering map mods all our pros poof;
2. Right now we have builds that can easy to fast kill all bosses. When we stunning bosses Arc traps, El hit, Double strike just killing them
