Honestly, the only fight I would like to see that gets fixed is the HM Titan and EM Titan. With the way how ping is and positioning on SE's side, people get screwed royally on this getting hit by stuff that shows on their screen that they have cleared the area. Furthermore, it's quite unforgiving with those fights with people getting knocked off with no chance of recovery at all. Way too much dancing in that fight that actually affects a Black Mage's dps cause they have to keep moving most of the time. EM Titan is a real challenge that nobody wants to have a "new" person come in and start the whole learning process again because that person will keep dying a few times before getting better when the group is already trying to get the boss down after the heart phase. SE knows about this "lag" issue, and yet people are having to get a 3rd party pingzapper or whatever just to deal with the lag issue caused by SE's end. Why do people need to pay for a 3rd party lag buster program when SE can remedy this issue by allowing a little more response time to avoid getting blasted by stuff that happens on SE's server but not on the player's side, but people still die anyways. This is the biggest gripe players have.
