I noticed my mage as arcane had almost kill many time in Undermine after pull many mobs. Like I did before alts.
Thier barrier is low?
I guess frost spec best for open world? Since Frost had high barrier?
Arcane sure great for dungeon and raid since they dont get attack. Tank taunted them.
I would have to say you´re wrong. All 3 mage specs are, performance wise, just fine for Open world /questing content.
You just have to play them accordingly and control the encounter, which is exactly what Mages have always been specialized in. Sure, frost “feels” easiest because everything is constantly slowed = most mobs never reach you. With both Arcane + Fire, you simply balance that out by using your instants, slows (Frostnova +CoF), mass stuns /knockbacks (Dragon’s Breath /Blastwave) and movement cds
Frost’s barrier is only like 20% better than the others.
But I will agree that Arcane and Fire just feel utterly terrible in the open world. Their lack of passive slows and requirement to be standing still to do actual damage, it really slows them down.
You can play them if you want, but you will be less efficient.
