The definition of bias:
"Riflemen are so bad because they cost so much to reinforce. Grens too gud."
Meanwhile grens are sitting pretty with 30 MP reinforce costs.
Meanwhile grens are sitting pretty with 4 model squads.
Meanwhile grens are sitting pretty with facing higher count squads with superior received accuracy.
Meanwhile grens are sitting pretty in t1 compared to t0.
But i guess since they upgrade in the field that makes them OP
Thats only 2 more MP per model and since they have less to replace they aren't nearly as bad a drain on MP as Riflemen.
The fact that Grens are basicallydamn near a 4 man sniper sqaud with unit wiping grenades at only 240 MP a pop is what makes them OP.
