The bottom line truth of the matter is that after 40 or so it's inefficient to lvl. Go ahead and grind all you want.. But think on this. When Shale comes out the main quest will continue on which will give you a lot of exp for completing each quest. Its really easy to level up on these quests, but if you are already lvl 50 doing a quest really meant for a lvl 30 then your benefit is greatly decreased. Also if you are 40+, you can lix in shale for an hour and get to 50 pretty quickly compared to grinding mobs that give you 100 exp... For HOURS
Three are people in cats monopolizing knights and rest in that room that are literally getting 50 exp points per kill and ksing other plp 15 lvls lower who get full exp. .... For no reason other then an addictive greed and irrational obsession to lvl at all costs.
Chillax plp.
Just to chime in on your last comment, most folks are only sitting in there camping the black knights for the quest, they leave anything else to lower people trying to level.
