I'm pretty much in the same boat as you. The expansion was good for the most part and the season I would say was definatly better than others before it, but this "final assault" was complete garbage. As soon as the boss spawned in, all I thought was "that's it?" Literally just the same exact activity that has a new name, after it's been built and hyped up for the past 6 or 7 weeks? Nothing but extreme disappointment from me.
