Comparing the T-62 and the Chieftains is something of a race to the bottom. The Chieftain has a notional edge in some areas, it’s worse in others, but in the end they both suffer at the BR bracket.
Ultimately, tanks that borderline require a defensive, hulldown playstyle that relies on armor shouldn’t be at the same BR as tanks with LRFs that outsnipe them, and rounds that trivialize even their best armor.
the protection of the t62 doesnt help it at all at these br, the chieftain’s turret at least gives protection to apds and some apfsds, again it still have bad mobility.
does that compensate for the less flat pen and angled pen? doubt also no mobility on t62 isnt really bad. that aside i wholeheartedly believe that the t62 fits fairly well at 8.7 and so does the chieftain, your issue isnt with these tanks being at 8.7 it should be with the many op undertiered premiums, like the t55am which is the same br as the amd1 despite being just better. or t69IIg.
So youre adding up the flat pen and the angle pen of the two apfsds round? you can only fire one at the time buddy, and btw even the 3bm4 has worse angle penetration especially at range…
it has basically the same above 500 at 30º as the l15 and has much worse at 60º… at all ranges, also courious that as to why you base the angle performance at shallow angles…
You are the one ignoring the 60º angles which indicates better the angled performance, the l15 basically start overperforming the 3bm3 at like 40/45º, keep in mind that youre the one claiming that the 3mb4 has better angled perfromance… while also ignoring the performance at higher angles…
and youre ignoring flat penetration and 30° penetration, which are far more common targets at the br, the m60aos hull is where you might struggle to pen at range with 3bm3 and its not a very common vehicle in my experience
did i said that it had better flat penetration? buddy youre the one that claims that it has better angled penetration, if you base that by the 30º mark the the 3bm4 would have the same angled penetration as the 105 dm23 which is false…
btw m60 are quite common at these br and it is far from the only vehicles where the armor have over 30º, and it also helps you far more agains 9.3 and 9.7 as it easier to hit the side of the hulls and overall more forgiven as the round will keep penning wore placed shot at turrets.
