Like any MMOG you’ve got new bugs and balancing issues to work out after a major revamp like this. Plus there’s even some bugs still around since the days I played like the Line Of Sight bug that allows NPC mobs to shoot through walls or the clipping bug where an NPC becomes part of a structure and won’t let you attack it. (will you FIX THESE FRIGGIN THINGS ALREADY!!!). It might have been better for them to start fresh with whole new worlds where everyone had even footing but I gather some things are just too costly or simply not desired (Hell I desire it!).
