Damn your logic teamoldmill, you're making me feel like my JT's useless already.
But seriously, yeah, I think every owner of this has thought the same thing. At this very moment in time I'm moving my 91K undistributed exp on my Ferdinand as close to 200K as I can get it before transferring it to the E-100 (I have the gold and I think this works out nicely; 6 crew to six crew; the 5-crew E-75 just won't do)
The JT needs SOMETHING. It has, for it's tier, no armor. It bounces 1-4 shots a game against anything resembling competent competition. It's taken for granted and gospel that it is useless in Clan Wars and I'm not in a position to disagree, not participating in those. It has a camouflage net made out of reflector vests and realistically if you were going to buff anything on it, it could only be accuracy and maybe penetration. Rate of fire buffs obviously always help but it does have 2-piece ammunition, so it might be straining credulity. (not that this is a simulation)
As is, it's good, on paper. It's less than good where the tread meets the Earth and if I had to sum it up in as few words as possible that no one would disagree with: it's a very situational tank.
Is there arty? City map or open? Team composition on our end and theirs? Any good cover / concealment positions? What are my teammates doing and what is the enemy doing?
It can keep pace with heavies and buff their firepower and it can lay consistent damage at a decent rate of fire at long ranges but all these variables add up to one reality: it's a gun. The chassis gets it from point A to B and provides perfunctory spotting ability but that's about as much as you can say.
If I had to pick 2 buffs to make it more competitive and unique without just going into Wishlist "I want a broken OP tank" I would say ... *sigh* the accuracy .27 and give it a bigger top engine, the old 980 HP engine from the tier 9 Panther 2 or even the 1200 HP one from the E-50 / 75.
The latter would be a stretch though since they tend to separate technological components from the real-life tanks and the near-entirely speculative Napkin-Waffle E-series and also since it would pull the HP-ton ratio up to near-Jagdpanther levels.
Tweaks like credit generation, repairs and ammo / repair costs do nothing to ameliorate actual in-game deficiencies though they'd be appreciated. I don't think we'll see changes but that's my 2 cents.
