The VAST majority of online players are 160lbs with great speed and there's no disadvantage to doing so. How many players in the NHL are 160lbs? You've nerfed the poke check and being able to defend cross crease passes, and made checking more difficult. Attempted hits and poke checks take you out of position easily and you've made it overall much more difficult to defend. For primarily defensive players, it's made it more difficult and less fun, which leaves us short on defensive players and way too heavy on tiny, speedy forwards. Balancing this would make a much better overall experience for real hockey fans.
