Block stat

I will play tank a lot, I see lots of stuff for the dps but not much for us tank players just damage taken (which isnt really that good). Block is a more and better stat to determine how well you tank and how well others protect themselves when performing. It seems like very few actually defends themselves without tanks and that could mean a big difference between life and death. Its better to see that ok I did take most dmg fine but I also had most blocks so it means I protected myself at least and hopefully others. In general as dps if I do most kills dmg etc and see I took least dmg its nice, but if I took most dmg as dps I need to improve somewhere if its very high above others, same if I play as a tank.
