Please outline in what way they are cheaper and better than Grenadiers.
They believe that 20mp reinforce per model vs 30/25 per model for grens and volks is a big reason they are supposedly cheap. They forget the 1.089 rec acc they have makes them drop models very easy esp early on, more so then any other main line. For being "cheap" they can bleed you dry handely. Them eating muni to is overlooked as well.
That cons start with 3 abilities ( merge oorah sandbags ) most main inf start with 2 or less, is also used to justify them being supposedly cheap. But those other inf have better base preformance then cons d. People forget that cons are the only inf that have side tech specificly for them, those cost add to the base price depending on how many cons you get. It jacks up their price.
Just to get them basic snare and worse version of incindiary nade, and the 7th man while imo a worhty upgrade adds even more cost to them if you want it early in t3.
