I've tried tier-5 mini-derp guns myself, and when firing HEAT, it makes the game so much easier that it almost feels like cheating. It's not just confirmation bias and complaining about other people doing better than I think they should.Stark wrote:MP balance issues are always about statistics and confirmation bias. Even when something is hugely OP and a major problem, you might never personally see it (and if it doesn't happen to you it's often difficult to know what it was). That's why complaints about balance are often driven more by community consensus than anything else - everyone says the ASW is cheap so it must be cheap, I saw a guy using it once and he won ergo its overpowered, etc.
It's no mystery why; the penetration and damage figures for low-tier HEAT rounds are public, and subject to rather casual empirical analysis.
M4 Sherman using standard M1A1 gun: 128 penetration, 115 damage
M4 Sherman using derp gun with HEAT: 150 penetration, 350 damage
Gain: 17% penetration, 204% damage
Panzer IV using standard L/48 gun: 110 penetration, 110 damage
Panzer IV using derp gun with HEAT: 150 penetration, 350 damage
Gain: 36% penetration, 218% damage
Now let's look at high-tier tanks:
IS3 using BL-9 gun and standard rounds: 225 penetration, 390 damage
IS3 using BL-9 gun and gold rounds: 265 penetration, 390 damage
Gain: 18% penetration, 0% damage
King Tiger using L/68 gun and standard rounds: 225 penetration, 320 damage
King Tiger using L/68 gun and gold rounds: 285 penetration, 320 damage
Gain: 27% penetration, 0% damage
High-tier tanks don't gain nearly as much advantage by using gold rounds, but mid-tier tanks can gain huge advantages from using derp guns and gold rounds. An M4 Sherman using gold rounds can one-shot another M4 Sherman if he gets a good die roll, whereas that is nowhere near true for high-tier tanks using gold rounds. Those mid-tier derp guns are highly imbalancing to the game; this is not mere "confirmation bias" or groupthink. There are numbers to explain exactly why the effect of gold rounds is far larger in mid-tier than high-tier games.
They could solve this problem quite easily: simply remove HEAT rounds from mini-derp guns. M4 Sherman players can still use gold rounds for advantage, but only in their standard M1A1 gun. This way, they can't get a penetration boost plus an absurd tripling of alpha damage by deciding to use gold; if they switch to mini-derp guns, then they should use them the way they're supposed to be used: with HE rounds.
