[Ecclesiastes]

Haste is godly for gathering; it finishes your attack faster so you can go to the next mob that much faster, and it adds up over time-nothing game breaking, but it's at least useful, unlike Accuracy. Accuracy will NOT help you in any significant way. Even if you plan on using it to try to keep your mobs at equal health, Swordcross will be killing them an uneven speeds anyway. That one hit during gathering just doesn't matter.

Cannon is nice for the block rate. Every little bit of defensive ability helps. So basically your list looks good, just ditch that accuracy ASAP and get Haste instead.
