It has nothing to do with no lifing and the fact that you can’t kill Magmadar with less than two Tranq Shots at that gear level, and Tranq Shot only drops from Lucifron which would require two raid lock outs for the Tranq Shots you need.
And this is assuming they can get 40 players to 60 in 1 week, get them semi-geared, get them attuned, and get the Hydraxian Rep. In essence, MC full clear isn’t happening week 1. My money is on week 2.
