Berserking Enchant and AttT

I took my druid shopping the other day at the enchants store in Dalaran, and bought me a copy of Berserking and Your Weapons, by Ben Dover and Taye Kitt.

At first I didn't realise that the armour debuff (25%) had been changed in patch 3.0.8, down to 5% less armour. Given that the effect stacks AND refreshes, a PvE fury warrior would dual wield this bad boy of course. Before 3.0.8 however, AttT got such a spanking from a whopping 50% less armour (2 x 25% when stacked) that the AP lost was just too much for the cost of mats compared to pure +AP enchants.

Silly me for not keeping track of patch notes! Now I just need to decide if I should get one right away or if I should wait for a better weapon to drop.
