Thanks Shurrikhan, I do use WTFast - but playing from Australia to an NA server is extremely painful (the 240 ping is with WTFast, I get 280-310 without it). Yep, forgot about the animation lock, so Suiton would most likely still clip 0.5s-1s of your GCD.

Part of the reason why I stopped raiding on my NIN - it just feels extremely bad that I'm constantly 50-80 DPS behind where I should be and therefore I have to force the other players on the group to pick up the slack. With fights as closely tuned as AS in terms of DPS checks, where everyone is busy doing their own thing and also trying their best without needing the added stress of compensating the laggy/inexperienced NIN (whichever one it is) made me choose to drop out of the static I was raiding with and just swap mains to DRK instead.

Wish they can fix ninjutsu somehow for people with greater latency, but I don't see it happening in the forseeable future unless they scrap the whole idea and just make the mudras straight out castable from the get-go.
