So i confirm it's a bug or whatever you call it because it always happen when you meet the conditions.
i did test all possible options for wrotation (even the advanced one) on 3 differents DPS classes (2 cac and 1 ranged).
i write my own rotations but i also test with some random from the forum and i can say my rotations works everywhere with no problem
If a Boss had more than 2148M health (full life or not), rotation engine doesnt work and magically begin to work itself when boss's life goes under 2148M. Nothing to do, just wait for it.
It's a heavy problem because in the nighthold, LFR Guldan has more than 2148M and if you are in a 2/3/9 roster, some HM Boss got more than 2148M life and all boss on MM got more than 2148M.
I fear about Tomb of Sargeras, because i believe majority of boss will get more than 2148M life.
So please @Droidz, say something about this, because its a real issue..
Thank you.
