I agree (partially).
Yes, JT and ELE are endgame option to deal with FF and su85, but if when you lose it you just call in a new one, then it doesnt make much sense.
Limiting it to 1 per player per game makes the player keep the unit alive and reward the allies for destroying it.
Its very hard to destroy a jadg just going in with su85s pushing from the front.
If you invest in like 4 t34s/85 and you manage to stuck the jad and then destroy it, you will probably lose the 4 t34s (assuming the axis have a panther, at and volks to panzerfaust) and thats 500 fuel, if okw just calls in a new one right after that, it makes no sense. You need more skill to destroy a jadg than to use it.
You need to spend 500 fuel and time to rebuild what they called in instantly for 280.
(Yes, asuming you have the MP and fuel ofc).
its not that there are no counters to JT...
- sovjts diving bombs (doc) are really strong to a engine destroyed JT..
- mark target is really strong
- come with on t34 from side....it turns around to destroy it...and div in with 1-2 Paks + 1-2 TD...it will be killed
- div in with something and activte for mother russia with penals + satchel charges...kill
- use B4 from sovjet and kill it with one lucky shot
- faust it and souuround it with AT and tanks...
- use 2 fireflys and hold it 10sec in stuns...while you kill it easily
- use artillery cover and div in with tanks...kill it...
and so on...
its not unkillable....only if u dont have a strategie...but for its cost...it need less strategie as u need vs a early bofors / sim city...much less
