A few minor things at the moment (ill come back with a more complete list later):
Necklace of the Chrono-Lord not Necklace of the Chrono Lord - It shows up as unsupported with your spelling.
Also
Titanium Weapon Chains I feel should be added. Yes they are primarily melee weapon enchants but with 28 hit rating per chain you cannot ignore them as viable.
Dragonscale Ammo Pouch doesnt show up as a selection, minor since the haste rating is the same for this item as it is for the Netherscale pouch.
More to come!
*edit* Woops! looks like the chains were added over night! Ignore that part and thank you!
Rune of Finite Variation shows up as unsupported as well.
*edit2* Cheeky's old spreadsheet had an option in the gear planner to assume 100% hit. Is it possible to impliment this again? Your spreadsheet doesnt seem to be accounting for the Focused Aim talents and therefore ranking gear with hit higher than gear without if you dont have 100% hit from gear. Minor detail that I assume could be fixed pretty easy.
