Can't you still attack ground with blind? I guess it works good on something with machineguns, like KV1 or Sherman. But if you use it vs TD, you can still attack ground.
Imo if vet requirements were removed, the unit may actually be a meta. Imagine diving t34 and you just blindshot it decreasing its dps drastically. Not sure if it is not going to be too much though.
que this exact same situation but instead its an AEC stopping a tank in it's tracks.
why would you attack ground with stun shot though? + a stug can already more or less solo a t-34/76 without needing the stun shot in the first place, stunning it and having any AT as support is just a very likely secure
