Feel your pain man. I've spent all my playtime today just trying to find ways to max my enchanting level. I'd love to stop at 80 but I need to get to the extra effects perk that requires you get to 100 but going from 80 to 100 is deceptively mundane. I'm convinced they did this to keep one from breaking the game because enchanting is extremely powerful. I'm not sure one can max out their enchanting level even in a single play-through unless they make a concerted effort as I've been doing. It won't come from normal play
It's a good thing really as Enchanting is horribly over powered in it's current form. Some people might enjoy that, I really did at first. But then it gets boring being so solid lol. Thankfully choice is the best thing and I've since switched back to my non Echanted Smithed Ebony armour because it looks awesome and still offers some challenge.
