I play exclusively on the PS3 and my average ping to the JP Datacenters is roughly 99 - 102ms. Putting slow loading times and FATE/mob loading issues aside, I don't notice any slowdowns of animations or dungeon mechanics that affects me adversely. I.e in a fight such as Titan, I am able to dodge them although there will be several instances where I still get hit even though I have run out of the AOE.

It seems to be your connection speed I would say. Have you tried pinging your respective data centres (NA/JP)?
