I tried to beat Byakko extreme and Sigmascape 1 Savage over the weekend by joining party finder groups and on Sigmascape I found that:

1. People blowing up all the ghost boxes and is being thrown off the edge.
2. Not sticking the green aoes to the edge.
3. Picking the wrong ghosts to enter the carriage and fight.
4. Placing the bombs in the wrong place and killing us all.
5. Not killing the putrid passengers fast enough.

In byakko it was slightly better but people kept dying to the first tiger fight or leg sweep.

Also in party finder groups you get people treating practice as “farm party” and leaving after first wipe, or in a farm party, repeatedly wiping.

I jus think savage and extreme content is a huge leap and people seem to think they can sale through it! Also it seems to highlight bright as day bad dps.
