Scenario: you are looking to see how much XP you need to get to be on the overall leaderboard and find a likely spot on page 121
Issue 1: you have to click the right arrow 120 times to get there.
Issue 2: you have to click the left arrow 120 times to get back
Issue 3: Going to a different class and back does not reset the overall ladder to page 1
Issue 4: Leaving the lobby and returning does not reset the overall ladder to page 1
Issue 5: Issues 1-4 are replicated in each class.
Suggestion: Typical navigation methods include the facility to increment/decrement by 10/100 depending on the size of your database and the ability to return quickly to the start.
edit.
Is there the facility to find your friends positions?
