I'm backing up a semi into a crowded parking lot full of cars. I need to back into the loading bay, and there's not a lot of room.
The only thing that stands between my semi and your sedan, is me backing up "by feel". Yes I will get out of the truck and look every now and then, but I'm on a timeline to get this cargo out, and back on the road.
My mirrors are only going to do me so much good. I *have to* rely on "feel".
I'm not saying your statement is wrong. I'm just saying that "feel" has its place.
In a game based completely on math, where a mathematical equation determines every possible scenario, no, feel means nothing. When you are comparing X and Y and making a statement about X > Y, you can't say X feels > Y. X is either > Y, or X is not > Y.
The statements about how blood DKs have had longer to play their class and are therefore more skilled are equally silly. No tanking class is very complex or difficult to play. I picked up a blood DK and was playing on an equal level with my paladin the moment the two had similar gear levels. Similarly, particularly for those of us who've had beta, paladins, warriors and druids have had quite some time to get used to their mechanics, and monk players have had some time to get used to theirs as well.
Yes, experience is a factor. No, it is not as large a factor as you think it is. If you're skilled and knowledgeable enough to handle one tanking class's active mitigation you're probably skilled and knowledgeable enough to handle all of them.
