The mod team STATED that they are an alternative to volksgrenadier, and they utterly fail to be that alternative
They may not be used much in 1v1, but Panzerfusiliers are used as an alternative to (some) Volksgrenadiers abundantly in 2v2 and up. Way more than before. The goal was definitely achieved. Not every unit or ability can be good in every mode. Regardless, I'd like to experiment with their stock DPS a bit to see if they can become a bit more a viable choice in 1v1 too.
