Danger Rooms a good thing. Basically a glorified terminal, meets D3 Grift, meets POE random maps (So I hear. I don't play POE). Plenty to work towards in the vendor and a good level of challenge, so long as you don't bite off more then you can chew.
I did have one frustrating experience on a blue map that had the random boss affix and the reduced area power damage. I ran it with Window and was going along fine murdering everything with drones (which aren't area tagged) until I hit Magneto, who was the random boss. What proceeded to happen was a total crock of shit. He was using his cage attack from off screen that was taking 3 quarter off my health, or he would activate his floating AOE which was literally killing me in 2-3 ticks. This is the same well geared Widow that passed the cosmic trial 1st time with ease. After about 10 deaths (he was also on the other side of the map...) I got out of there, before something around the house got broken. Was seriously annoying. I started playing a year and half or so ago, so I wasn't around for the original incarnation of Limbo, but apparently his AOE bullshit was similar then
Anyway that aside, I enjoyed running scenarios. Other then a bit of tuning here and there, the main issues I have would be we need separate storage for the DR chips, which apparently Gaz are already working on. Also, having to clean up mobs after completing the objective seems to take a little longer then it should, but I'm not as fussed about that one for now
Oh and adding Odin Marks and/or commendations to the loot table would be awesome. Maybe add DR to the Dailies, though as a 60 only mode, they, understandably may not want to do that.
On an unrelated note melee Spideys a beast now. Got through the trial 1st time with a lvl 1 legenday, only 3 slots with 60 gear and aside from a shit rolled spider serum, crappy artis.
