While players complementing one another is a normal start, it doesn't take into effect that with the currant abilities the Jag is over preforming due to its engine upgrade (negating its slower speed), long range, HE rounds, and piercing shot. It is effectively an arty unit as it can bypass normal terrain issues other than sitting in the bottom of the hill on steppes and firing up. The unit NEEDS a range reduction at best to match that of other mobile heavy tanks at 70. The 85 range is over kill and should be toned down to allow for more counter play.
The piercing shot as I state earlier needs to be removed, units such as pack 43 should not be able to avoid terrain Collision due to some special rounds they get, simply not fair and not practical for gameplay balance.
Currently the only counter to jag tiger is to effectively "hurl" cheap tank at the unit making it as Imageless bean pointed out "impossible" to effectively trade fairly. OKW will always come out on top with its cost effectiveness.
This doesn't mean the stun is ok, it’s a dumb mechanics that only lasts for 2.5 seconds and only reduces its speed. As others have pointed out a HP reduction is a solid idea as the armor value for it is rather high in comparison to ele even.
TLDR: Match stats with ele (Basically), remove cheese abilities.
I understand your point, but i dont think these abilities would be cheese. I think if their stats would be OP, the tank would be OP in 1v1 or 2v2 aswell. But its not.. and even this thread complain about larger game modes and a scenario where JT is covered by other players.
I dont think a decreased range would open new counter methods. Simply because you could not put up a fight with smaller TDs against an 500+ frontal armor even if you have the same range.
Removing the "penetrating shot" is an option, but again, if it would be OP, it would be OP in smaller maps.
You counter the JT in 3v3 the same way as you do it in 1v1... if there is another player around, you have to push him back first, with your allies. I dont want to get into exact scenarios, but just for the sake of an example:
If there is a JT covered with infantry, mobile arty (Katy or Calliope) and / or plain AI infantry can push them back, then you can roll in and circle jerk the JT. Mark target + bombing is still a strong combo as it is against Ele. Bazooka blob is ALWAYS underestimated. People think it cannot penetrate, it has no accuracy and unable to deal damage. Somehow i have been countering Panthers successfully with bazookas.
These are the methods i use against JT. Non of these are related with sight, piercing shots, etc... Personally i think JTs fuel price should be increased a bit and manpower price decreased a bit, and its HP lowered a bit, because it wears a concrete sarcophagus for frontal armor.
TL;DR:
Increase fuel price, decrease manpower price, decrease HP
Leave the abilities alone
