Well i guess i was wrong, there are certain classes which are buggy..
1. Assasin (Raven Skills bugged / Hit Animation bugged)
2. Mage (Hit animation bug / Chaos mage skills dont work)
3. Kali --> Bladedancer skills wont work. (at least someone told me they wouldnt work)
Classes that work 100%:
1. Warrior all skilltrees are fine
2. Archer all Skilltrees are fine
3. Academic --> Shooting star ( Idk. about Physician bc. I only have SS and didnt see any Physic. around... :/)
I hope that the admin let us know that he is working on something or at least he should message us in any form.. otherwise this server wont make it.. and that is the last thing what i want.
