JT just needs its stun removed... then it would be fine. Stun was introduced to balance that it could shot through shot blockers. No need for this unit to keep this annoying stun.
waht do you purpose for vet 5 increased damage or he rounds doesn't matter becasue no one is going to reach it
axis heavy need buff
getting a kt and jagtiger in a game is a acheivment in its own
and they should be quite formedable once you get them but nope https://www.youtube.com/watch?v=seb_tA8ezNA
No it is not. I get you would like to have all your units Vet5 in a single game but I don't think OKW was designed this way. What's more there are units that gain veterancy ridiculously fast, like mentioned Fals or Puma.
Puma gets to Vet5 in almost all of my OKW games and I'm not even trying.
