As much as i want to argue that attribute points are really awesome and cool to spend and allocate as you see fit when levelling up... they really aren't cool or important.
Thinking about it i always spend the points in what is required for that class to be good. So if it is a tanking class i will put points in constitution, pysical damage warrior i will put more points in Str.
What i can see from the talent tree is that if you go into the tanking talents they also automatically give you a constitution bonus so the more you go into that tree the more Constitution you will have. Also makes respecing easy and fast. I like that.
I do agree though that this being removed does take away from the people who want to make... lets say "interesting" builds, like a warrior with tons of wisdom or something. Is that a bad thing, for some people sure, for me though it doesn't make a lick of difference.
End of the day you can still make a tanking warrior with lots of constitution, because thats how the classes and specs are supposed to work.
Thanks.
