First off, I've really enjoyed this thread and keep coming back to it nine months in. So thanks so much for doing all the work to start it! When I started playing my fire mage I wasn't super satisfied with scorch spamming, and I used to run an Arcane Explosion spec as a cheese build back in BC so I thought I'd try it out. I've actually had a lot more fun with it than Fire, especially since people are so thrown off by the different style.
Instant polymorphs and frostbolts are so handy in WSG, instant fireballs make for great burst, and my mana pool sits at around 4k which makes me a decent FC. Plus hunters and rogues are always stunned whenever I blink at them and spam AE. They crit for around 280 apiece, so while not super mana efficient the uninterruptible dps is excellent (also, in groups there's a lot of clearcasting going on).
Curious to hear if anyone else has goofed off with Arcane. Presence of Mind just gave me a lot of fun and improved counterspell is not to be ignored in such a caster heavy bracket. I'll probably go back to fire eventually, but as a "for the love of god play objectives" player I'm fine with sacrificing kb's for clutch flag saves. There's also a lot of +Arcane greens avail, I think I cap out at +231 Arcane Damage (but I carry a full eagle set with me and swap around as needed) If there's interest I can post the gear/build.
So glad people are getting good mileage out of the thread. It would be great to see your build and I'll look into adding an Arcane setup to the list.
