As most of you know by now, tier 7 is facing a major remodel after this year. The reason?
They broke it with fantasy and anime tanks that weren't properly balanced. A lot of tanks in tier 7 that were introduced early in the life of the game have become powercrept. To show this, I will be cherry picking the worst hit of each tank class.
A fine example of this is the T20 American medium tank, and I'll be throwing the light tanks in with this category.
Medium tanks. Good mobility, good gun, multipurpose.
The T20 American medium tank was a fun little stop in the tech tree, back in the first era of the game (May 2014 to October 2015). It had a punchier gun than the other medium tanks of the time, and while everything else was meh, it could still be driven quite well. Jump forwards to the current era (October 2016-Present), better known as the influx of fantasy tanks like the Helsing and "modified real-ish" tanks like the Blaze. Suddenly, the T20 is outclassed in every way by a tank with a tier ten engine at tier 7. It has worst-in-class DPM and worst-in-class armor, which are usually offset by decent mobility, which it doesn't have. It does have a single advantage: APCR penetration values are top tier. Which means when they nerfed premium shells, they put the final nail in the tank's coffin.
Can a good player still make it work? Sure, that's not being debated. Is it good? No.
Heavy tanks. Good armor, punchy guns, bad accuracy.
The heavies were hit as well. The regular old IS in old times was a monster, and so was the KV-3. But when we look at the numbers, these two tanks are two of the worst tanks by far for winrate of the tier 7 heavies. Why is this? Well, for one, the 122mm gun is straight up garbage on both. The dispersion values are .417 and the bloom on movement are a massive .24 and .27. In a world owned by mobility, this causes a huge problem, because when one of these tanks is moving you can't hit the broadside of a barn if you were inside it. And to be quite honest, the 400 alpha damage at tier 7 isn't nearly as intimidating as it is at tier 6 on the KV-1s. These are the defining guns of the two vehicles, but they're completely unreliable, and this is combined with a below average DPM.
How about the TDs, then? The defining factors of a TD should be good gun handling and for turretless TDs the hull traverse should be decent.
Let's pick on the Sturer Emil, then, with it's abysmal winrate of 49%. I personally enjoyed this tank during a time without Drac spam. With terrain resistance, the horsepower per ton is: 8. Oh boy. Definitely gonna be able to fight the new speed meta with that. LTTBs and Dracs beware, he'll get there at some point, with all 30 mil of side armor in tow. The gun arc is equally bad, a whole combined 12*. I have no complaints about the gun in this case, though. The biggest issue is the gun is almost equal to the Helsing's in theory, but the Helsing has a turret, can go 60kph, has a HP/ton equal to that of the T20 medium tank, and half the hull is an autobounce.
So, for all of these tanks, there's a premium tank equivalent that's better in nearly every single way.
The T20 has the Dracula for competition. Similar gun, similar armor. However, the Drac gets: Twice the engine. Higher top speed. Spaced armor all over both sides. Better DPM. Better Aim time. More hitpoints.
IS and KV have the
Eyesore Lupus. Lupus gets: better aim time. Better hull armor. Better turret armor. Double the gun depression. Higher top speed. More hitpoints.
Sturer Emil has the Helsing. Helsing has: Better hull armor. Ridiculous speed. A turret. Better dispersion and bloom. Mobility of a medium tank with broken steering.
