Those saying latency issues don't/never exsisted must not have seen this thread

It was even worse for me, going into the fight and a few seconds later Red latency and completely unable to move or act. This wouldn't even disconnect me, I would just stay Red 0's for most of the fight, If everyone isn't dead already including me. If/when network data did start moving again, Ifrit would end up freakin invisible and untargetable! I didn't find that acceptible on a 55mbit connection. I know some other people back before I took a break that had the same issue I did. And when it wasn't totally unplayable, being hit by plumes and eruptions that you clearly dodged did not help the situation. My whole team had the skill, but latency killed us all, not Ifrit.
Maybe those with no issue are using battleping or similar service or lives in/very close to Japan. idk. I recently started using battleping myself, paying an extra monthly/tri-monthly fee for comfortable latency.
Maybe next time I try Ifrit hard, He wont be given as great a latency handicap from me. Maybe even so with 2.0, since the servers are suposedly going to be way better than the current ones. Maybe everyone that was stricken with latency issues, which does play a big role in success and fail in this fight, will go in and roflstomp it 100% of the time.
