Hi everyone :/

I'm coming here in need of some serious help and advice for Garuda trail because it's insane. I just got access to it today. I went through it 6 times today with no success at all. Before I did get to do this quest I had researched the fight online via a guide. Only thing I forgot to do was watch a PoV video. Its becoming a pain and I'm stuck. I'm a White Mage and it's hard to keep up with my healing because I have to constantly switch my rotations from the tank to a dps that didn't get out of the way fast enough and got wiped. I even got kicked out because one group got mad and was starting to say some...things. I know that this is the point in the game where it gets hard in order to reach endgame, I already expected this to be coming. Only I didn't expect it to hit me like a firebrick. If anyone can give me some help on a better way to get through this without accidentally wiping the whole group due to lag and rubberbanding issues is really appreciate it. Thank you!
