Downloaded latest patch. Got as far as loading screen for Arcana Obscura instance. Client hung.
Killed client, restarted GW2.
This time, got into the instance and as far as attacking the enemy ghosts. Client hung.
Killed client, restarted GW2.
Same again. Start killing enemy ghosts, client hangs.
Killed client, rebooted system, restarted GW2.
Now GW2 consistently hangs at the character-select screen – I can’t get in to do anything at all.
Not quite the point of no return I was looking for.
