Frankly. 800HP pershing was better. At least it gets 50% reload bonus at V3 so It had some advantage about DPS parts.
I would much rather have the extra raw hitpoints over having to hope for miracle bounces (because 300 armor was not that special). The -50% reload was just ridiculous, especially when it could also get another -30% on top from Combined Arms. No other tank in the game had a reload bonus that high. A vet 3 Pershing with CA could reload in like 3 seconds.
As said before the only downside to the bigger HP pool is that it needs more repairs (is it even a downside? Better to spend more time repairing than having a dead tank). And that will be addressed next patch with the damage reduction modifier.
Both IS2 and Tiger 1 have max speed 0ver 6.0 so Pershing's 6.0 max speed wasn't a big benefit at all.
Pershing has better stock speed. It just didn't get any speed bonus with vet, but now it will. It will have 6.6 speed so it will keep the edge over the Tiger and IS-2.
And both tanks gets reload bonus at V2 30%. But after nerf Pershing gets it same 30% at V3.
No they don't. All of them get the reload bonus at vet 3. And the Persing will get an extra 5% to compensate for the wind down because it isn't affected by the reload reduction.
