Dear admin said that this question is edited as in official times. But everything else was organized against ko authority. The examples are endless (Talias, Drain skills don't hit every monster, reduces the stats of anti-defense suits, Archer 62 skills, Mage 72 Skill, Boss notification, etc. none of these are official.)
Also, as someone who played on Profko's previous servers) Priest's skill usage has never been this bad on previous servers. Even a single player can constantly cause the skill to fail
