@Obeliske
In regards to your point of mana.
mana is not a issue on ascencion, just stack ap trough the roof pick Shamm Rage and fill your bar every time you use it. If ur still lacking you can pick up mana gems/seal of wisdom and never have to worry about it ever agin thus mana cost reduction talents are meh.
Windfury just isnt worth it for builds that arent stacking %physical mods to like 130%/TG haste becuse it just doesnt do enough damage to justify using it.
why would you use windfury when it procs less then Flametounge and does less damage? i seen windfury procs do like 3-4k hits with low proc chance and with a 35% pvp mod makes them hit for less then auto attacks in pvp. but i seen flametounge doing around 4-6k hits in pve with proc chance being super high on that ability its not even a comparision.
