Certification skill Barrier is not working as it should work . It should add total invulnerability but if you Hit or use any kind of skills it should be removed . But if you get Barrier and you don't do anything just stand then it should last to end .
Same goes for Duelists / GK's and Bishops Barriers ... if they hit or use skill it should desapear from Buffs .
All mages are abusing this for Farm . Fix it .
