So it's my own generalized consensus that nobody ever likes getting queued into these. I've seen people drop right after loading in. Some people agree in the party chats that they'd like to see a revamp of the fights. I can't say that I'd be excited to bring friends into this content for the first time.
Frankly I think they could do with some updates to the bosses or mechanics. Nobody ever sees the pots needing to be healed, it is not necessary mostly because of the huge ilvl creep. I have seen people who aren't invisible-tethered on that boss just idling...
Since this is content that pretty much all new players have to do for 80 expansion, it would seem like a good investment to revamp it considering it may not leave a great impression on free trial players/or people who only buy standard edition.
It seems like the reactions were positive with the ARR dungeon revamps. I don't see why we couldn't expect a future update to the CT raids if the developers are counting on the free trial experience to bring in more money.
