Sinking Sands was unplayable, I start a fight (then I wait 25 seconds for the fight to actually begin), then I want to use an ability (fifty/fifty change of it actually happening instantly, otherwise wait 25 seconds), then the screen freezes up again for about 25 seconds.
Anyway, this didn't happen in PoF luckily so I got some xp. But that zone is much better at 54, too many close fights to get a decent xp rate going. And I can't do the Ashen quest chain as yet as I can't defeat that 55 tough mob as yet.
Ah well, at 50% for lvl 54, I'll get there soon.
But I do hope they get it fixed in the maintenance, this is truly annoying.
