If you are a casual player, no.
Argus is by far the worst zone they have ever made. I am always the guy that defends current content btw and can't stand when people put their rose tinted "BC was amazing" specs on, but not this time. The monotonous terrain combined with no flying makes is hard to navigate and you keep asking yourself why you bother...and log off. This is the reason I have played a total of maybe 4 or 5 hours since Argus came. I usually play 2-4 hours a day and has done so since 2005..up til now.
I don't really raid or pvp much anymore so unable to comment on that for this patch..or xpack even.
