both howizers are bad, the got always be 1 shotted by of mapps. the only that works is Priest, it is way less efficent than both howizer but it can move.
Grens DPS drop 25% when one model died, you can't just compare with these meaningless number comparison.
1 gren got in 35 range around 2 dps, 2X3= 6.
1 volk got in long range around 1.31X4= 5.24
so I can compare the damdge. even 3 volks got less damdge than 2 grens.
only 2 volks got more damdge than 1 grenadier.
