Agility is always king, and I tend to like having a fair share of crit. I'm not too sure what the stats look like at 69, but definitely try to have a fair amount of crit especially as sub/outlaw. I wouldn't imagine assassination being too good without having a nice chunk of haste/crit, but you can mess with it. Versatility is a very good stat if you can stack it, but I tend to prefer having a nice amount of crit before I try to include vers.
