Timer of skill

Hello..Its about the casting bar , Skill activate and the Player position lock.
Most of the Dungeon Mob including the Trial Dungeon Monster has a Devastating Aoe Skill and its too pain to eat it continously.
My suggestion is to sync the skill casting duration and the skill activate with the adjustment for player lock up pos.
Lets say the the casting took 1.2sec to complete and activate but the lock up pos is 0.3sec,The player still got hit if they move late even before skill activate.
Mostly player wait the animation to appear before dodging as other MMO.
My suggestion is to adjust the Player Position Lock timer to a reasonable or close to Skill casting time.
Maybe it can solve some " i still got hit even i was outside".

Sorry for my bad english.
