It's ultimately useless for anyone to gauge anything from what they see on their limited friends list, though. But I definitely got the idea you knew by the way you responded to someone else. You ask a thousand different people and you get a thousand different responses. When they announced World Visit, I actually made new characters on each of the worlds they grouped my main with and leveled them through the Road to Sixty as well as getting them through the story. The main idea I had was to be able to sell on all those realms, but in the end it's just too much work to manage. Which is something I enjoy about games: if they give you the freedom to do something that is optional and has lasting benefits, it better take a lot of work. That work shouldn't also be erased and you should keep on benefiting from it if you put in the work. Something I think WoW is starting to realize with Ion's comment that their weakness so far has been not having things that persist through expansions.
Though in regards to queues to log in, there are still some 20-50 queues in the eight that I play in (which is Crystal). I'm told that Aether has pretty much full servers as well, but I'm unsure of the other DCs aside from the two in the U.S. that have preferred status after most had locked status for a while. Even around 1 AM or so when I quickly do some retainer stuff, a couple of realms have a queue, though it's usually a swift entry thing. The thing with Blizzard is Real ID, as you can see anyone on no matter what they're doing. So it doesn't surprise me that classic is doing the heavy lifting (though I am slowly getting one or two levels a day; got a Paladin, Druid and Rogue to 60 back in Vanilla before focusing entirely on Rank 14 and getting crushed by my server by people who shared accounts).
As for customer service, I've had to contact them several times and it's always been super quick responses when it comes to GMs. The same goes with their live chat service -- just a couple of minutes wait and you're in, and they handle things fairly quickly. Though I haven't used the calling service as that tends to take longer than the chat. They also just recently announced an attempt to use social media to help people, under a trial program.

When it comes to customer support that's worse from personal experience, then I'd have to say anything involving EA. I remember Mythic in particular was shady, as was the old Warhammer MMO. Unauthorized charges, tickets that went weeks without being answered, no real live chat that I could find (or it was hidden or not available when couple times I tried them). Then their policy that any response they give will be auto-resolved within 24-48 hours if not responded to. Keeping in mind that they don't respond or likely read for weeks so you never know if there was a response and you have to keep on logging into your account every day to check. They also kept asking question and trying to prolong me getting refunds for unauthorized charges so that I'd just give up after a few months of back and forth and them not responding. I've also had 5+ days for Blizzard to respond to tickets before. But their live chat is okay and I just do that now.
The though examples I've read above seem to be about: Timeframe of active services (hopefully changed by the new initiative), chargebacks and people just not liking the answers they were given. Personally, I don't quantify these as particularly bad compared to the horror stories I've been through and witnessed.
