Sacrificing a lot of weaker orcs in fight pits will trigger a rebellion the next time you walk in your garrison. Orcs do care about each other after all and they don't like a greedy dictator to rule them. I bought shadow of war because I loved the first game Shadow of Mordor. I believe many reviewers  just went angry at micro bla bla, but I hope they were able to experience this game from different points. Only 40$ for the game on ps4. I have over 3000 gold, 90,000 Merion, spent few buying ExP boost and upgrades, I am still at level 47 not even finished with the storyline and already winning online conquests against players with higher ranks not impossible to beat as long as you don't care scoring the gold prize. It could be very challenging yet FUN.. I just love this game..
