In the Pershing you're basically getting a Panther in tank vs tank, but it fires HE shells at infantry. Panther is a tank destroyer whose anti-infantry capability is purely mg-based dps, so it's terrible against retreating squads/vetted/elite infantry/yellow cover, and has to stay stationary within snaring range to deal damage.
I like how the two or three people complaining in this thread keep comparing Heavy Tank vs Panther as if Heavy Tanks fired only AP rounds and weren't used mainly for bleeding infantry and as spearheads for pushes. It's 99% a L2P issue.
Use heavy tanks vs infantry and not in long-range brawls with tank destroyers. If a single Panther is killing your Pershing (moves faster than a p4, with armour and health of a Panther) or your IS2 (takes an average of more than 1 minute to for a Panther to kill an IS2 by itself), what the heck are you doing with your 15 apm? Just....reverse?
But you really don't need to use the panther as anti-infantry though, you have the best non-doctrinal anti-infantry tank in the game and rocket arty in the same tier, the panther instead has amazing tank and AT stats, because Wehrmacht is designed with extremely strong specialist tanks. Ignoring that fallacy aside, people are annoyed that the panther can basically neutralize a visibly more expensive allied heavy tank (that you can get only one of), on top of standing right in front of them. A tiger's easily gonna beat allied TDs if they stand right in front of them, but panther has considerable armor and 960 HP, it has almost as much durability as your praised IS-2 does
all that would be a fine thing, if the tiger wasn't better than both of these tanks, for the same cost. truly bizarre, innit? not only does the go out of it's way and kill infantry better than the is-2 is supposed to, but it has a mobility buff and potentially smoke, so you will really hardly kill one of these.
Now, for the """spearhead""" method - you aren't gonna do that lol, you are NOT a king tiger, you wont delete squads if you simply look at them, hell, you are an obese T-34/85, not a heavy tank. The enemy isn't stupid, two paks will follow your IS-2 and will not simply let you farm meager models with the horrible scatter your gun has.
I saw maybe three is-2s being used in the last 2 or so months, but i saw dozens and dozens of tigers in the meanwhile, saw more tigers in 1 match than IS-2s since june.
15 APM might even be advanced for axis players, god forbid i ever see such an enemy in my game
