This is purely feedback on my experience of Danger Room Scenarios as a relatively new player. I have no interest in discussing it, take it or leave it.
Scaling, in a word, is offensive. Both health and damage are ridiculously high. Its out of touch with new players, and has no in game indication "Warning hours of item farming required." TTK is tedious, getting swarmed by common mobs means instant death in many cases, especial for melee heroes. Its more easy to kill some end bosses then it is to kill primary objective mini bosses from a previous round. Or some bosses seem to just drone on and on. Its quite disappointing to be playing a super hero and leveling them all the way to cap and getting ran over by trash mobs in a green scenario. We put in the time to play something thinking we will get a return on investment and its like you flip a couple switches and now the hero is sub par. COME ON!
