mobile fire lines are a thing in this game. Ive found if i sit still with my riflemen and dashel doing nothing in the back i end up getting stomped. Things are too fast for this "stagnant fire line". Ive had better luck with 2 riflemen dashel and a sargeant for movement buffs. wk 5 riflemen wk 6 dashel. with walk 6 you can easily charge forward and tarpit the shit outta something with dash. Ive had him tank a deso engine, hes tanked a rail golem, and much much more. Dashels job is to give out buffs and protect his squad and sometimes when things get grim hes gotta put his helmet on and run for an objective. 9 points may seem expensive but ive found that hes been worth it 10 fold. and he can fit into any guild list with his team.
