the biggest problem is IMO 2 things:
cp0 snares removing one of okws primal weaknesses in the early game, which will pretty much make m3 builds obsolete and give okw even more snowball power.
Call in tiger which will make mech techbypass builds even more popular then they are currently since tiger is even more flexible then command panther
This "weakness" being a cheese exploit basically, to be frank. Do consider though that 5 men Panzerfusiliers have worse rifle stats than Volksgrenadiers, so the advantage of nullifying the M3 cheese would come with the disadvantage of opening worse against Penals and Cons.
I do agree though that the Tiger call in has a risk of creating a new Command Panther meta.
