Aye so for starters you should ignore anyone complaining mage is bad now because of nerfs… Liquid is running 3 arcane mages in ST fights, so you can choose whether the people in the forums don’t know what they are talking about or liquid is clueless…
In addition if you look at wowlogs arcane mage is near the top for most fights, so arcane is doing great right now!
For starters you should REALLY link logs to fights you find concerning and consider sending VODS people are typically glad to help especially on the discord if you ask nicely!
