I have not asked you whether it is possible (ie. whether the game allows it) to have a bundle grenade unit before BP1 but how does one even have such a unit before BP1. This question must be interpreted as a question regarding the factual occurence in games actually played, not theory crafting from game mechanisms. In essence, this question basically stands as: how does anyone actually have these units before BP1 so that part of the thread can have any value.
This does not apply only to bundle grenades but to all grenades and assault grenadiers do not have access to their grenades before BP1. And just to clarify I am not claiming that they should have access to grenades from the start.
On the other hand the fact ostheer grenades require BP1 does have an affect on the gameplay.
If you are asking how can one have unit with grenades be available before BP1 I am telling via doctrines.
If you are asking me if it is a common occurrence to get the units with grenades before BP1, my answer it is almost in every case for assault grenadiers, less common for ST, PG.
If you are asking if it has happen to me, I would say, yes I had a couple 2vs2 game where I called ST before PB1.
If you are asking me if it is balance issue I would say not an important one.
Yes, that your thread has no relevance to anything and is completely redundant and pointless
Also, if you like extensive formalism, so be it.
If that is how you feel about it I would advice you not to read it.
Once more is there an actual point you want to make about Ostheer teching or are you simply arguing "pointlessly" in a "pointless" thread?
