You’re both illustrating the problem I stated originally. Have we had to do this at all this expansion up until season 4? I surely haven’t, and it feels like I should now, I don’t need to but man would it make it a mile easier.
And if we do have to do this now, why is there no communication in-game? I’m not ruling out it shouldn’t be the way it is. I’m stating that the timing and no-communication in game for such a huge change mid expansion was a bad idea.
The easy way to fix this is to scale heroic dungeons up in difficulty and throw the m0 mechanics in. That ensures a smooth transition in both knowledge and expected power from the dungeon.
