In what way will a post-patch Schreckless Volk + Schrecked Sturmpios blob behave better than a pre-patch Schrecked Volk + Schreckless Sturmpios blob?
You were lucky if you got to see a mixed unit blob. I've almost only ever seen massed gren blobs (sometimes with an officer, if they are feeling super tactical). Given how few negatives (mp cost is insignificant mid game, and at vet 4 they will survive well) there are to sturmpio blobs, I'm sure we'll see people at least attempt to switch to them.
Fingers crossed it isn't as effective, and we finally see an end to shrek blobs. But based on all my experiences against OKW players I'm pretty confident sturmpio blobs will do well and become OKW blobs MKII.
