First of all, the achievement Another Kind of Shattered is very stupid. I don't know what others think, but hidding an achievement behind the failure of an event is stupid. These things should be a reward for COMPLETING a part of content, not waiting until an event fails.....an event that never fails because you cannot stop the players from playing and enjoying the new map. So, in conclusion, I believe those branded soldiers should have been a part or a pre of the rift event. I don't like waiting for 1 hour for an event to fail. I know this map will probably be like the others, totally empty after 1-2 months, but still is a stupid idea to hide achis behind event fails.
The second thing I hate is the way dwarven rooms works. I do metas every day to get that kitten key just to get stuck into the purple room where that grave digger drops nothing. Is this how it was intended to work? If not, why don't we have a fix already?
I find the new mastery pretty useless too. I mean is useful only on the new map pretty much. But it has no real use. Is like a weaker springer.
