I'm still playing my Archer/Illusionist... beat the main quest a while ago but I'm still just exploring - I'm pretty convinced it's the most fun combination in the game. That being said, it's a little crazy at this point how powerful I am; I feel I really should increase the game difficulty but I might just wait until I make a new character (probably a mage but with some more magic mods like Midas).
I'm 100 Archery and 90 something Illusion at level 45 or so... I have a good chunk of points in Alteration, Alchemy, and Enchanting as well. I just wear a full suit of glass armor; helmet and gauntlets enchanted with Fortify Archery, chest with Fortify Illusion, boots with Carry Weight, and then ring and necklace with Fortify Archery as well. My Daedric Bow isn't enchanted, it's just improved up a tiny bit (Exquisite I think) but only because I'm intentionally limiting myself - I already one-shot practically everything or only take a handful of shots to kill Dragons/Mammoths (god-forbid I poison my arrows, then it's just silly).
I usually sneak around dungeons keeping Muffle and Invisibility up between spurts of Detect Life, I was calming and frenzying a lot in dungeons but I can usually just shoot down most enemies now without worrying too much about it. Now-a-days calm is coming in most handy in the wilderness keeping surprise animal attacks at bay or for simply clearing out Giant Camps quickly.
