KRZY-Takes: Grousers, Yeahhhh, or Nahhhhh

KRZYBooP: Howdy Boom Jockeys! Throughout my time in World of Tanks, I have gone through some builds with my tanks. I have tried builds that enhance the properties of tanks that already are amazing and done some that help with shortcomings that some tanks have. Since the big equipment shake-up, I have not really thought about using the Grousers on any tank.  Is this a mistake on my part? The cool little GIF that plays when hit "alt" says that my tanks will plow through all-terrain like a gold round through armor.  What would you sacrifice in order to put Grousers on your tank?
