Not strange, its because of all the peacebears.
After i hit 20+ all ive seen is peace'ing between people.
Im only lvl 32 myself, but if its -5/+5 lvls of me im going to attack.
No drama about it, its a pvp server people.So start getting some aggression going, its fun.
PS: This is offcourse when i can get online because the que's are horrible.
