That is because usually you combo those low crit units with backrow sniping. However, Writer didn't include Gunrods in his deck, therefore its gonna be hard to deal effective damage on the opponent and give them time to counterattack.

And true, MW has issues with crits, but that doesn't mean nearly all of them should be crit 1 (16 of his 22 monsters has crit 1).
