"Skill Lock" exploit

Based on that logic, it's basically the same as an inexperienced player click spamming on a target and forgetting to cancel or not realizing they're using defense, which would make it, if anything, an exploit rather than a bug. Though i'm not sure it should even be considered an exploit, since lots of monsters have flaws built in to their AIs(like extended wait times before executing skills), which are obviously intentional.
