Some real degenerate gameplay has been circulating around.
People have figured out that if you have multiple level 1s online in your group it scales average group level down making it so you can open world boost with a high level character and your alt in the group receives full exp.
This has been going on long enough, and has been very noticeable with JJ going on.
Any low level zone with hyper spawning quest mobs have just been flooded with high level characters mowing everything down.
Ridiculous that instanced dungeon boosting was slapped into the ground, but these open world shenanigans are still running rampant.
Fix it.
