Today ARGO Online added a new ranking system that ranks players based on their total XP and a second list based on players win/lose ration in RST mode. It also looks like they are working on a third ranking list for guilds as that page currently states it is under construction.
Kicking off the new ranking system, alaplaya is holding a month long event that will gives players the chance at winning some loot. Players will be placed into “winning” levels, based on their character’s level, with the goal of accumulating as much XP as possible within the month. The higher your current level, the higher your “winning’s” level. You can find the info on the ARGO contest page.
Once the contest ends, the characters with the most XP earned in each “winning” category will win a designated amount of AP , with the grand prize being $150 worth of AP.
