Now that the Legacy Client has retired, here's some features it had over the new client:
- Item sets. While your files from past item sets are still working in the game, they are not accessible in the client.
- Ability to see how many normal games you've won on your profile page.
- Ability to see your top 11 mastery champions on your profile page, not just the top 3.
- Notifications didn't cover the Loot button, the Store button, and RP/IP indicators.
- The friends list/sidebar was collapsible.
- The store wasn't a maze to navigate (why are the Hextech Chest sets under the "Accessories" tab, and not the "Bundles" tab?).
- Your RP/IP displayed the amount correctly most of the time.
