Really?
Garuda is easy, just explain the fight to newbies thats what I do and they usually manage to do it after one/two wipes.
Also I'd like to point out we all did without nerfs, you did it without nerfs and with its 1.0 mechanics intact - also whay they are I have no idea since I (and much of the player base) joined XIV with its 2.0/ARR relaunch.

Nerfing sub lv50 content seems pointless and a waste, I mean if people cant handle Garuda NM whats gonna happen when they get to LV50 or Aurum Vale?

Also she happens to be one of my favourite fights and music
