Yeah we are not really disagreeing about that.
However its really good at offsetting OKWs fuel penalty and getting their tanks out sooner; KTs can already come very fast in team games and this just makes them come sooner.
And Luftwaffe also comes with counters to the B4 that is one of the major counters to OKW, however CAS also does that
The problem is two fold:
1: Luft supply doct is a gimmick doctrine that is only for supply drops,
The other thing it had got nerfed hard (Med box's) While I agree that fuel boosting
is really dumb, Once that is taken away OST will be down another useable doctrine
without some changes to the med box's to make them more attractive again.
2: OKW's screwed up income mechanic -
Because it has a % modifier on its fuel income things like supply drop completely ignores it.
If it was normal income with the fuel costs added on the top (i.e. Puma costing 105 fuel with no penalty) and tone down the conversion rates accordingly this kind of thing would not be such a problem.
