One changed animation - Meditation.
All of the mechanic gear was changed (the equips that are attached to the mech). Each equip can give +1 to a skill. The skill it can give +1 to is dependent upon the level of the equip (level 30 gives a 2nd job skill, level 70 gives a 3rd job skill). Like the reverse equips, there's only a 10% chance of getting the +1. It's not much, but it's nice to have.
A lot of the data added implies that they are done swapping around skills. The icons for skills were finalized, sounds added, and all reverse items updated to reflect mechanic skills. Also, it looks like there were a lot of animation and delay changes for the Laser ability (not the FSAoE one).
Also, can anyone provide an explanation for the earrings below?
