This is our proprietary skill rating calculation. This has nothing to do with official game ranking or MMR.
The purpose is to show player skill levels relative to other players, not estimate MMR.
Increase your Healing received from others by 15% while at or below 50% Health.
Heal for 300 for each enemy hit with Fireball.
Increase your maximum Health by 600.
Heal for 270 every 1s while Shield is active and you are at or below 35% Health.
Reduce the Cooldown of Charge by 1s for every 1000 damage your Shield takes.
Your Shield now uses a resource that Regenerates over time instead of using a Cooldown.
