In fact, I loved blood DK since ICC, tanked with it all the way through cata because of its hipster AM, and wished they add some tweaks to make it "new" again. I rerolled monk only recently (because lvling is a hassle) but I already see on various streams how strong it can be. Only tanks I dislike are rage user (druid/war) because I'm bored while playing them. But's that's some personnal thing, I'm sure plenty of people find them ultracool and dynamic to play
to each their own.
I like all tank classes, it's just that having a paladin tank rather than any other one (10man speaking here, careful guys) is way smoother on every fight.
