Which stage you at with Garuda? The difficulty I had was being a summoner as you just don't do the burst dps to get the feathers down to a reasonable amount in lower levels.
It is like farming for gear yes (pretty much valor(sic) token farming), but my only real complaint about it is being locked to a single instance - you practically have to do AK runs until token capped at the start of the week and instances are currently taking upto 20 minutes to reserve even with a full party ready to go. It just makes it feel a little stale but it is quick once you have it down.
I probably should have said that darklight gear looks the same for your armour class type so you will all look the same sorry
I have finally managed to do complete this quest, tank was from Free Company and he already did it so was much easier, still a very difficult fight if not executed correctly.
