The root causes of the current situtation (pure clans playing nh, main clans ragging pure clans) are these:
The pking scene is dying (no bh, rev cave, pvmers in wildy). There are a lot less players now in the pking/clanning community. Without midweek pking there is not much reason to play (for many people doing inners and cwa is just not sufficient). I dont blame these people staying away from this game, not bonding their accounts just to have 2 pk trips at weekends.
The few hundred players who are still doing clanning are mostly veterans and have hatred for each other. You should look into yourselves and find out what's wrong with what you are doing (only playing the game to ruin others' fun).
Until any of these two gets fixed nothing is gonna get better here.
