THIS IS AWESOME!
All the gear I collected from 77-80 was resto gear, but I heard about these axes and respecced.
With the blue/green gear from quests / assembled without enchants (and using resto glyphs)
I out dps'd my almost full epic Ret Pally friend and he got really pissed when I told him he should go holy :O (I was always the healer for our groups)
A few tips from my testing so far...
1. Hit rating is extremely important, every time your weapon misses you're potentially missing out on a huge chunk of damage
2. Crit rating is also very important, as long as flurry stays up you do INSANE damage.
3. I tested all kinds of combinations on the 80 heroic dummy,
frostbrand MH, flametongue OH is indeed top dps
4. Watch your aggro...
5. Enjoy pm's like WTFZOMGHAX white weapons?
Can someone confirm whether frostbrand/flametongue crits proc flurry? If so crit is that much more important
Also, move to elite IMO, this is incredible.
