Modlist's with difficult endgame
I have played a few known lists by now but only modlists I played troughly are GTS and Lorerim 3.1
GTS's level scaling is a bit weird imo, Legendary Dragons and poison mage mfs are very challanging but otherwise most enemies are easy enough to handle. I feel like part reason for that is vanilla+ combat + very high stamina regen you can have. You can just bash, dodge and power attack an enemy one sidedly.
Otherwise I think it'a a challenging enough list, I yet to kill any major boss other than dragon priests tough.
I have played Lorerim 3.1 extensively by now and after the 30 level mark difficulty starts to become a joke. I like requiem, it makes the world more grounded for me but when there is this much content, its difficult to do all the quests in challanging order.
I think both of the list are on the difficult especially at start but I want a more challanging endgame. I heard Lorerim 5.0 is more balanced in that way, might give it a shot.
