New Patch today had a bad bug that involves AC. If you change to 2H weapon and then back to 1H you lose about 10% of your AC. I made a hot key to deal with this issue. AC FIX hotkey: /alt act 1278 (Soul Flay) - toggles /alt act 1278 (Soul Flay) - toggles /band activate tanking (1h + shield) Note: "tanking" is the name of the bandolier for 1h + shield (use yours). Make sure to "fix" your AC every time you change from 1H to 2H then back to 1H. Very annoying... How many years till this is fixed?
I had the same problem on my paladin. To fix it as a paladin, I toggle weapon stances and that puts AC back where it should be. I expect it'll be fixed shortly, but my expectations are often dashed in EQ.
