I´m still not looking that much forward to the Katyusha as to the Yak-1. All rocket launching vehicles in FH2, from the Sdkfz 251 to the Calliope Jeep, have very limited effectiveness and are more or less only used for direct fire on enemies within sight. Thus being almost suicidal.
It´s an annoyiance to aim within the arty sight and trying to get the vehicle to 0/0 when you have to change seats for every adjustment.
So Katyusha is nice but meh.
