Something simple I suggested awhile ago involving character selection on the website. I have a shit ton of characters, and I know for a fact that there are a lot of people with a shit ton of characters. Why not add some more filters to the website to help sort them out?
Even something as simple as being able to list them by level would be extremely useful, so that your high level characters are at the top of the list and your low level characters are at the bottom. Filtering out characters below level 20, or characters above level 20, etc, just simple shit to make the character selection a bit better.
