Been in love with arcane gameplay since I started the mage in late wotlk(except the mess it was in Legion before 7.1.5)Maybe thats why I love Havoc DH gameplay as well. Mashing few buttons with good CD usage is awesome fun gameplay, for me.
Frost in WoD was also fun. Was fire mage main in start of legion, but its for me dull and boring, especially since they nerfed the burst alot few months in. Arcane was just messy and boring at that time so I rerolled hunter.
They pretty much nailed the arcane how it is now, and I love it!
