I chose destruction as one of my main skills and apparently I use it a LOT because it's now at 75. I searched the forum about max levels and what that means and it appears there are differing opinions on what happens when you max a main skill. Some say your character will stop leveling, some say you will level after that but no skills will go above 95.
So when DO you stop leveling? I checked the wiki and it is also unclear on the subject. I'm tempted to stop using destruction at all for a while but I've gotten pretty used to it. I have short sword as a main as well and have gotten a couple of really nice daggers and thought I would try to use them anytime I could.
