There is 1 chain skill for Cleric that has been frustrating me since 2013 when I started to play Aion, it's Impervious Veil that compulsorily runs after Remove Shock and doesn't let my character use any skills for 30 sec. I hate being this helpless in combat, still worse in a group as a healer. It's very difficult to avoid pressing on it manually after Remove Shock as it's in the same slot of a quickbar, and the bot (Combat Support) always uses it when Remove Shock option is on. I can't remove it in Chains tab of Skills window. Please add an option to switch it off in the Chain Tab!
