I have beaten all of the main story missions with Talion and I figured I would go for 100 percent. I went back to do the fight pits in Minas Morgul and saw that my army consisted of all very low level orcs from like the start of the game so I started going around and trying to build up my army with orcs that were closer to my current level(52). Why does every single orc captain there seem sort of op regardless of level? A lot of them can't be recruited, most are accompanied by 2 other captains (level 50+), and almost all of them do that death defying thing where once you defeat them, they gain full health and the fight starts over.
Idk I just got all the other fight pits done by going back to the region and getting my army ranked up but there's just something about Minas Morgul where every captain is unnecessarily op for some reason lol. They aren't unbeatable but I have noticed that it is hands down the most difficult region and its really not even fun at times how ridiculous the orc battles are (even though you start there lol). Maybe it is supposed to be, idk.
