Reduced attribute requirements on gloves may be lowering damage percent?

I swapped from low lvl gloves with a lower phys dmg modifier to better gloves with a higher phys dmg modifier and both having no other dmg related mods and i am losing damage. The new gloves have reduced attribute requirements as a mod and I am wondering if that is causing some issue? The low end gloves are 5 to 13 phys and the better ones are 13 to 19.

Make sure the old gloves do not have an attribute on them that you need to use one of your persistent buff skills. If so, unequipping them would disable the buff skill gem until the attribute requirement is met again.
