I recently replaced Battlelord's Plate Boots(+20 expertise + 20 ArP gems in those sockets, ilevel 226) for Grinning Skull Boots(ilevel 232) after enchanting with the same enchant my gs dropped 6 points.
the stats on the boots seem to more than compensate for the loss of the 2 sockets
with the 2 sockets i could technically get 109 str with it but it has haste and a lower Critical Strike
with the new boots its slightly lower Str but replaces haste with ArP which is better for Arms warrior isn't it?
