as this month's ranked arena was ending soon I was playing a lot of ranked arena. I have found problems bugs on several skills such as Frost Pillars, Tornado, and Meteor Shower. All of these skills suffer from the same problem when I use these skills they sometimes land far from the target and sometimes behind me. the cast time on some of these skills is too long resulting in a stunned opponent getting up and using an evasion skill and dodging the skill. With this bug and long cast time, these skills are useless in the arena.
