i got a question as a new arcane mage:
in case i have 4 arcane charges, i'm under 90% mana, without arcane missiles to trigger and nether tempest is about 5-6 seconds away from fade, what i have to do?
go for an arcane barrage, knowing nether tempest will drop before i can build 4 arcane charges again or spare a gcd to refresh it before arcane barrage?
hope it is clear, sorry for poor english.
