I will look into the Darnassus travel issue. I guess most people don't travel through there these days. If you unlock the Hyjal Portal (takes only two quests starting in Stormwind at the bulletin board) you can get there that much faster.
And if you don't have the DPS to kill Rageface before he casts Facerage, then I would suggest running the raid maybe as blood DK. Facerage is not used against characters in a tank spec. I want to implement a way to let the bot choose your spec in the future (since all specs are available to each character in Legion), but that will take a while. The bot does try to summon the Gargoyle or the Army of the Dead for Deathknights, but Singular spends most resources so the bot can't pool enough to actually cast the Army. I should maybe consider using the Army on Pull. It might last long enough until the first Facerage.
That's sounds really nice! Hope that CR's will be possible in the future aswell!
After 2-3 tries it actually killed it, think its just luck. but will respect to tank spec next time.
One more question, how can I config it to prepot and pot on some bosses?
