Maybe it's worth noting that only allies have call ins that can effectively dodge teching ?
Still need to find the match where ost relied on puma/command pnz/stug E whole match and didn't get a stug.
Armored company call in and m4 sherman can EFFECTIVELY replace top tier tanks.
That's the big problem here, not call in, but call ins that can avoid teching.
Quite a difference isn't it ?
Like i said, only axis call in that can eventually let players skip teching is command panther, but okw player can call only one, and won't benefit other armor with aura.so you basically get a worse panther than normal roster with useless bonus that won't benefit anything (except puma).
Protip: that's why modders decided for a non teching fuel penalties for such call ins before relic saved such crap
Protip: saying protip makes you seem conceited/condescending
If that's how youre defining callin meta, then sure. However, that definition of callin meta is...irrelevant to the discussion honestly.
Even with your definition though, relying on a tiger callin is debatably callin meta (though not too meta). Spec ops and scavenge are full on call in meta. Sure, by your definition, ostwinds technically arent callin meta because ostwinds dont and arent supposed to replace any of the okw t4 vehicles, but theyre more effective than teching t4.
Spec ops and scavenge are by far the best and most meta okw commanders. Both involve dodging t4 (in spec ops' case, severely delaying it usually to the point that it never ends up being built) and using callin vehicles.
