Solution 1st make PVP ZONE and Increase the drop rates so people have to FIGHT FOR DROPS , not just pve with full titans without competition .
Solution 2 Put in l2 store jewals pack lvl 3 for 30 days ( i know already exist lvl 1 we got some of them on attedance event ) and put it with ncoins or l2coins , like this people not complaing about price of rb jewals , ncsoft will get more money , people who already have it they can trade them between chars so is not so bad , If u buy them can keep stable your vip ( if u buy 1 every month ) . If u can sell them ( i mean whole pack) u can make some adena .
Main problem on servers atm is NO PVP at all , people become boring after farm so much time elements etc etc , and pvp is 1 hour per week on castles , since on raids pve destros not flag at all , and no point buff the raids because with so many destro and so many events ( +++++ the weapons , dolls , lvl up , improve the char totaly) they can kill it anyway (maybe take more time but for sure they can kill it )
