A wet dream would be to have mobile team weapons like mortars or mgs shoot from inside it. But this is not going to happen. The price reduction could work though, as it is pretty much just a worse version of non-doc m3.
What would be the point of the dedicated 250 mortar halftrack then?
I mean it's a good idea, I'm just saying that if Relic was willing to and intended it that way they would have done it by now, probably.
Other than this yeah I whole wholeheartedly agree, the call in is not worth it's price, be it with a Grenadier or Panzergrenadier squad inside which it cannot support, all it can do is be a taxi for them and get them faster to somewhere than the squad having to walk to that specific place, nothing more.
Either an MG or a reinforcement ability or both with some price balance would be the best approach Imo.
However this has been mentioned several hundred times now with nothing done about it so I doubt it.
