So I've been talking to the devs and others for a few weeks and, basically from the information i've been getting, it seems that problem is not really UE3, but rather =ow the game was built originally back in 2011 or 2012. Since theyre adding more and more content to the game, because of how they built the game using UE3, the client is having trouble dealing with new content like 3rd specs, newer dungeons and raids like WC, CC, H0, SP, etc, open world areas like moon refuge, mushins tower, blah blah blah.. So instead of actually reworking UE3, apparently it's easier for them to just upgrade to UE4. I just don't understand why they won't just be blunt and say that their working on performance.....are they scared that if they say something more people will stop spending money? Is it a surprise? Are they still working on it?!!!!!!!! Jeez..
