Hero Rank is determined by your DPS and Maximum Level Reached. We had to let DPS and Level work together for your Hero Rank because if we only picked level it opens up possibilities for farming with multiple accounts. This way you need your items in your account for your DPS to determine your Hero Rank. This will still get tweaked a little with testing, but it will always be about DPS and Max Level
Hero tokens will be earned with the full version, after this test.
