The above is incorrect. Screenshot with TF+Zerk Note: You MUST use Tiger's Fury first, otherwise you will be locked out from using it while Berserk is active.
Also all crafting professions will give you +80 to whatever is your main stat, aside from JC which gives +81 for some reason. If you do the math on the Tailoring and Engineering enchant use/procs the DPS gained is equivalent to +80 main stat.
