I havnt found it any better or any worse than any other time in wow. Wrath seemed the easiest, however i mostly played tanks, and to be fair, until TBCC, i usually am the tank - in SL i lvld warrior, monk, dk, druid, and pally - in that order, and for this reason.
As for solutions to the "problem", there isnt one - The community has shown over the 17 odd years the game has been out that they consider the tank to be the "leader" of the group, the pace setter, and the one doing marks / making decisions. This can be different if someone else offers or makes it clear they want to be in "charge", but by default, it is considered by most to be part of the tanks job. This, coupled with the nature of tanking, adds a lot of responsibility and pressure to the role, when compared to dps in particular. Personally, I find farming dungeons on a tank to be very fun, once you equal or outgear the content, especially with friends. But when doing challenging content, either due to inexperience of other players, lack of skill, or the typical friday night drunk / stoned players, it can be a very unenjoyable job to take on.
As we all know, if there is a wipe, the actual chain of blame goes as follows:
Hunter
Warlock
Hunter
Rogue
Hunter
Boomkin
Hunter
Rogue
Hunter
Warrior
Hunter
Shaman
But likely, it is actually:
Tank
Healer
Dps
Truth is a lot of wipes actually are the tanks fault in leveling dungeons in particular, and especially early on in an expansion when they have just spent months as a fully geared tank steamrolling content, only to find themselves challenged by a lvl 67 dungeon. Remember, this is coming from a tank, and I can usually boil MOST wipes down to "I should not have pulled that extra pack - can i blame the hunter? shit.....no hunter......warlock? yeah, blame the lock" - "jesus lock, careful with the multi dotting mate!"
