Only changes the WC51 needs are
1) Range reduction to 40 from the current 45. This makes it harder to poke infantry from a safe distance, makes it easier to counterplay and increases micro strain on usf player.
2) Health decrease to 200 from the current 240. This means WC51 gets 1-shot from schu mines. This makes regular 30 muni mines a good counterplay option for the wc51, meaning the USF player has to be more careful and escort it with a sweeper.
