Elsword pushed a pretty sizeable PvP update yesterday, implementing changes that make rank even more important. The changes include everything from extending the season to improved matching and sparring.
Season 6 will be a longer season, running 12 weeks instead of 8. Star Ranking has been adjusted so that those with Star Rank are in the top 20% while a Guild Ranking has been added.
As for matchmaking, players can no longer cancel their queue once matched and draw times have been dropped from 15 to 10 seconds. Players who somehow find themselves waiting for 180 seconds will automatically be matched with an epic NPC.
Another change is the addition of PvP records, which will allow players to keep track of their progress.
