I'm not sure DAK wouldn't survive with a less oppressive FV, a unit that is well performing anti everything when it hit the field isn't good for balance, it leaves the faction forced to work around it in every match and leave the rest of the faction in bad state because of balance synergies.
I rather have it be much more dedicated AI and less able to counter LVs and buff jaeger AT back in the middle.
The statement you've made here is very true, however its global problem.
Stuart.
Grayhound.
Wirbel.
They are all anchor units for respective factions.
Tho US actually does have here a lot of options, Grayhound remains the strongest one.
Brit needs to get BOYS and HMG and DAK is crippled against it, can't move in with infantry because mg, can't use other LVs because BOYS, which leaves either mortar spam or Flakvierling and following hit to the face by stuart.
DAK relies way too much on crutch shock unit like FV or l6, because infantry is horribly inefficient on its own and a manpower drain for a faction that is mp starved.
