Actually got Shinryu NM in a roulette last night, first time in a long time.

There were lots of newbies and half the party died to Tidal Wave at the start, tons of death all around, but we cleared it in one go thanks to experienced players with higher gear levels and a sproutling tank that knew their business. I was on WHM and while I had to solo heal a lot of it due to the other healer dying left and right, I never felt we were in danger of wiping. Heck one of the newbie DPS shared Akh Morn with the MT on accident and lived. Hope some people learned a valuable lesson about proximity damage indicators though... :P

Shinryu can stay as-is. If it didn't need to be nerfed when it came out, it certainly doesn't need to be nerfed now.
