Other thing: When using Battleping, you should try different servers. Not every choice is bypassing the reasons of this issue.
I tried the server that has the fastest ping so the problem is not there (<40ms). Also, my pc is custom built for gaming and its config is more than sufficient to run ff14 at max settings. The ff14 benchmark released by SE went very off the charts. I suspect it is not a ping issue but dropped packets of data. The problem is specific to dodging aoe effects.

I raided in WoW all the way to Pandaria and am familiar with the 'don't stand in the fire' 1-shot boss mechanics - not ONCE have I experienced this type of problem before.

The problem is most certainly SE's.
