I think at the moment the Comet is a bit too much against infantry. But overall i think T34/85 is a bigger issue. At least Comet is not so cheap.
To start with, there is the Comets main gun which is pretty effective (especially against smaller squads). The following are the extras in AI it receive:
+ upgradeable commander ability, which makes it more accurate (useful for AI aswell)
+ throwable grenade (AI ability)
+ super speed to chase down retreating units
+ compared to the panthers moving accuracy modifier it has 0.5 while the panther has 0.7 (= more accurate while moving)
Now in addition of all these, it receives these vet bonuses:
* vet1 Phosphorus shell instead of smoke
** vet2 +35 rotation (speed), +30 accuracy (more AI)
*** vet3 +30% speed, +20% acceleration, Auto nade throwing on infantry (AI ability)
I think this much AI is plain overkill against infantry. If you decrease the accuracy of the main gun it would still be good.
Anyway, i just tried to reflect to your post. I dont really want a Comet nerf, but i think Panthers 0.7 moving accuracy modifier is unfair. Better moving accuracy on tanks like T34/85 and Comet is more painful, because they chase down your retreating infantry. Panther will never chase your infantry with coaxial and hull MGs. It needs moving accuracy against vehicles.
Most of what you wrote is based on the assumption that +%accuracy improves AI performance.
This assumption is completely wrong.
For low-accuracy guns (< 10%), accuracy makes absolutely no difference vs infantry. It's only scatter that matters.
As I already explained in my post, Comets get stellar scatter at Vet0. WP-shells withstanding, they get absolutely zero improvement in their raw AI performance.
To reiterate, the reason why Vet3 Comets seem godly vs infantry is because Vet0 Comets are already godly vs infantry.
As for grenades:
- Auto-fire nades have a long timer and deal reduced damage
- Manual-firing grenades will cause the tank to remain immobile for 3 seconds, during which you are a sitting duck (btw you can't abort a grenade toss; you really -are- a sitting duck).
Thus, nerf the Vet0 gun (and WP), but give some the performance back at Vet2-Vet3.
