I'm on Masamune and the ping is absolutely horrible... I am in the same position as the OP, end game content is painful and even though I'll be dodging everything that comes on my screen the millisecond I see it, I'll still get hit / KO'd by the attacks... In fact, as a scholar, I'm basically moving 90% of the time and making my pet heal and when I know its safe to heal , burst it out .. Rinse and repeat... not exactly how I want to play a game, I tried tanking and it's not even worth my time investing with such latency issues.

Apparently I'm sitting on 350-400 ping.... Even though I have a download rate of approx 10mb/s :/
