Ok, so I found that in the end Requiem wasnt going to work for me so now im looking for a way to work around it.
At this point I am looking at mods like Revenge of the Enemies for combat AI changes and maybe a few others to make combat deadly serious and balanced. The problem im facing now is that I have a number of overhaul mods that I already know I cant function without.
For a while I saw Requiem as the foundation then realized that it caused problems I couldnt ignore. So now the only reason I am keeping it is because of its static leveled lists functions and thats pretty much it.
I found that The People of Skyrim and Immersive Citizens can work together so they are very much a strong base for the new playthrough I want to build. Throwing Morrowloot, Unofficial Morrowloot Overhaul and scarcity on top makes for a nice touch. The problem now becomes that UMO and Requiem have a great many direct conflicts and in the end I have chosen UMO to win said conflicts. The problem is how do I get those choice elements from Requiem to stick while letting UMO have its way.
Thats the bigger picture im dealing with but the primary purpose of this thread is that I have been for the longest time absolutely clueless in respect to Perk Trees and how to get the right Perks for the right combat style and how to get the whole picture to behave the way its supposed to... At this point im just asking for someone to tell me from their own experience what they say is the best Perk Tree for brutally realistic combat and why.
Basically I want to make combat the way it should be in the real world (with a little room for forgiveness) If you take a blow to the head and dont have a helmet capable of protecting you, your dead, the end... I know of a number of mods that can give me this kind of stats but then it just becomes a question of balance. Perks, skills, and other things I dont have the foresight to consider in this regard.
And, of course, in the end, can I just stack a bunch of crap on top of Requiem to override whole cloth portions without breaking the game?
