We haven't seen what relic prepared in regards of new commanders for OKW yet. Maybe there would be custom commanders or they give some long-awaited juicy stuff like goliaph flak88 and jagdpanther.
Besides, sturmtiger, as i see it is British killer. Even more with some bugs you can use with it, hehe.
I am not going to pay for a commander, let alone commanders. The whole commander debacle is just painfull.
If they make these commanders war spoil 'dropable', it will take ages to get them, you might never get them. This doesn't give any comfort.
Custom commanders? If they would implement such a thing, which can be tremendously op, it will be behind a pay wall. Again, not paying for commanders.
Paying for commanders is just a very low move by Relic. It doesn't even depend on how you look at it, it was and still is a simple and below the belt money grab. Evidence of this can be seen in how useless 75% of Soviet and Ostheer commanders are.
