Belladonnas drop by the truckload in high density areas. One Tcow run dropped me 4, and i was running solo, ergo i had no nodrop advantage. I can give you at least 30 off the top of my head i keep on mules, and i barely ever play at all now because real life unfortunately.
50h is literally nothing. You barely scratched the surface.
I will admit that for a solo player , especially a new one , the beginning can be very overwhelming. But result may differ from case to case. I've seen new players complaining that the mod is too hard, others that the mod could be harder. Theres a lot of polarization in this matter but it all boils down to the amount of hours put into it , which usually in those cases isnt enough to say the mod is hard or its too easy. (unless youre seeing it from a clod player's perspective)
Dont consider Ennead Challenge as the below lvl 80 -> jewel + cc. Consider it the either very few or a lot of runs you need to do on k3kBA until your specific class' CC drops. Again , i can understand where youre coming from with the "cheesing" of just getting a new character to cube it for you tho.
120 isnt the endgame by any means. Also , using xp pots to level isnt actually cheesing , i mean thats what they are for. But in anycase theres 5 more levels on top (if youre playing on realm i mean, although i will also grant you that it doesnt take that much time to reach 121 if you grind enough in a day)
I understand where many of your gripes come from , and i believe many of them will be adressed in Sigma. But coming to all of these conclusions in 50 hours of gameplay....just no. Im not trying to be rude or anything. But you should at least get to Destruction before putting your 2 cents, because thats where the game really begins. Playing in destruction i almost trip over belladonnas.
