IMO the best thing for 2v2 would be nerfs to both ISU doctrines and removing spotting scopes from Jäger Armour. That would instantly improve 2v2 a lot by making these doctrines less of a braindead auto pick on all the lane maps.
It's very strange why this was not done back when the doctrines got reworked.
Another problem is the ISU vs Ele/JT match-up doesn't work because both ISU doctrines have IL2 bombs + T34 non-doctrinal ram. One of the ISU doctrines even has mark target which means you can just frontally kill Ele and JT with vet 2 Su 85 and ISU on AT shells or a combination of SU 85/Jackson/Firefly or whatever else you might have.
Jäger Armour isn't much better either because it counters snipers, artillery and tanks all in one doctrine.
I play Jäger alot ... because u have to in 2vs2. U cant compete against a well played M36. The only thing that helps is the ele on narrow maps. Same for the ISU but the ram il2 combo can counter u.
I would like to play some Pak43 commanders but u get deleted so easily be planes and firebombs.
So nerf Jackson,
nerf the ISU commanders, nerf scopes or remove it from Jäger and than it would be much better.
