Every raid, every expansion, every difficulty.
Post time you started, time you finished and how far you got. (At this point I'd say a lot of people should at least get Emerald Nightmare normal if not heroic to be their stopping place.)
Yes, this includes doing the LFR version - which is solo queue even into Legion now if I remember right.
Optional stuff you can post:
Your route/strategy.
Gold made.
Class used.
You don't have to do it all in one day, but if you split like that then you need to post both time it took to complete the challenge by straight hours just playing as well as start and finish times. (So if it takes you 14 hours but you did 7 hours, then rested for 12 then another 7 post 14 hours completed but started at like noon on day 1, finished 7pm on day 2.)
Anyone down for this?
(Yes, I'm putting this here as a reminder of something to try on my next day off, but it could be fun.)
