When you're in all epics and looking to jump to MWs, that's fine and good, feels rewarding, doesn't feel like you spent your time badly.
But then imagine if you're all MW'd up, maybe with 1 or 2 legendaries, and all the game has to offer is the same 2 or 3 MWs for 20 minutes effort (maybe longer on the hardest difficulties attempting to maximise drop quality, lol), ones you're most likely going to delete instantly as you'll already have them, they won't be an improvement rolls-wise and zero progress has been made. At this point, the game should see where I am in terms of progress, recognise that, and adjust the loot accordingly. Blue and purple drops are pointless. Wanting to experiment with builds and rolls, I need to be seeing dozens of MWs per hour, to roll the dice that many times to improve what I currently have because the buckets the rolls draw from allow for some terrible crap rolls. This is where many people are after only playing the game a week or so.
I go into freeplay now on GM1 and GM2 and the game just drops me epics all over. I give the controller to my 7yo son, put the game on easy freeplay and he's getting the exact same quality of loot I'm getting, only his efficiency is way higher as he can mow stuff down incredibly fast. Only one of us is truly enjoying this experience.
