So... I went through whole thread and the main conclusion is that you want a tank which can:
Yolo ruch into 2 Fireflies.
Counter 60 range TDs
Wipe infantry left and right
More HP
More armor
Is faster than medium tanks
Is cheaper (so it can hit the field around 12min in 4v4 and 15-16min in 2v2)
Nice
I propose simple thing. Buff it by making it avaible despite tech buildings (so its is much cheaper), BUT make it avaible only when your doctrine reaches 15CP (no more yolo rush KT before 20min).
Then you would have 260F tank which fits its price, since you dont need any more all tech buildings, just CPs.
You are over-exaggerating the entire thread and several things in that list were already shot down as being a bad buff for the overall game. This whole thread could end up being a moot point if the OKW gets redesigned, but if it doesn't some units might at least get buffed/changed. This thread should be arguments for and against certain things for the unit; not, "historically Brad Pitt was awesome and Tokyo drifted his Easy Eight to one shot a Tiger from behind, while it missed his tank 3 times".
Yolo rush into 2 Fireflies.
-I don't think anyone straight up suggested that it should be able to bum rush 2 Fireflys.
Counter 60 range TDs
-A range increase to 45-50 was suggested, but a lot of people also dismissed it as being too good, but even then no one suggested 60 range ot directly counter TDs.
Wipe infantry left and right
-If this is supposed to be the unit's intended role then a buff to HP would come in handy, but for its cost it is an awfully expensive AI tank.
More HP
See above.
More armor
-This would lead to Company of RNG/Bounces and has generally been shot down.
Is faster than medium tanks
-No one said it should be faster than Medium tanks, but as one of the slowest tanks in the game with the slowest turret rotation speed and no 60-70 range like turret-less tanks it can be impossible too ever line up a second shot. A small speed buff to movement and turret rotation speed would help, but not like Panther blitzkrieg fast.
Is cheaper (so it can hit the field around 12min in 4v4 and 15-16min in 2v2)
-The performance for cost is not that good right now, but lowering the cost hasn't really been brought up yet as spamming them early in big team games would be a problem.
I do think your idea of buffing it but locking it behind CPs is interesting, what would you buff on it to do so however?
