I have the same problems Freezing and Crashing of the game client since last patch, before the patch the game ran without any problems. I guess i`ll wait for a new patch and hope that one solves the issues… crashing/freezing every 5 minutes makes the game unplayable
edit: aparently going to Documents\Guild Wars 2 and deleting your local.dat file fixed my game. Many thanks for this AshleySegovia
