License
The Premium license is a powerful tool if you plan on playing each day of its duration, it doubles your overall gains, gain limits (like xp gain per OS session) and much more. The 2 extra loot searches for PvP and PvE (and other modes with loot searches) can mean the world of a difference if you want to farm rare loots, even if you don't have any other bonuses present, the license itself grants you the chance of higher gains as in higher chance of getting something very rare. The other important thing is the higher limit of experience gain in every mode because experience is a must-have at all times. Premium license doubles the Open Space experience overall gains as well as the gain limit which varies with each rank.
