I think the bigger issue here is that it looks like they are going to nerf Garuda Story mode...

Difficulty adjustments to certain dungeons and trials
We will be re-adjusting various 2.x dungeons and trials, such as Garuda, for new players.
I also haven't seen anything relating to adding a minimum ilvl for accessing the level 51+ part of the leveling roulette dungeons.
The amount of times its thrown me in there while I'm wearing spirit binding gear for vale. ;-;
Luckily I've always got gear to switch into, but I've seen people with ilvl 55 weapons in Dusk Vigil... >_>
