but they are not supposed to. in t1, players will have access to both and gain nothing from using exlusivly ostroppen (where now they gain 10 fuel towards faster pgrens) meaning they are more apt to be alongside grens, who are better combatants- there is room for both.
Thats is the point. Osttropens showing better combat results then grenadiers against both rifles\tommies. You gain nothing by having grenadiers mixed with osttropens. Grenadiers provide you nothing, but riflenade over osttropens, and later on LMG, but you already have T2 units near so whats the point.
Even during tournaments, we saw ostts+ sniper, and grenadiers were never thrown into the mix. With ostts in T1 we will only see more ostts + sniper combos. Thats a sad reality.
While indeed ostts were used as a fast capping and T1 skipping unit, its not their main selling point.
