Here is a cut at what tanks you want, or don’t want to have for strongholds. I am sure there will be some arguments but take it as a starting point. The numbers will rank the value of how much you should want that tank.
I also understand some tanks aren’t in the guide, that’s because they really don’t fit into the YOU WANT THIS or the YOU DON’T WANT IT, they are in the middle.
Heavies
1) M6
Now that the kv-1s has been burned on a stake the new flex heavy id say is the M6. It is fairly fast with good gun depression and ok armor. The tank has alright dpm and good soft stats on the gun.
2) KV-85
The new sort of kv-1s in a way. It has lost the good mobility the broken gun depression and any real incentive to run the 122mm gun. The 100mm is alright but with only 250 alpha Id rather be in an M6. KV-85 is still a good pusher and is a good meat sheild if you want it to be.
3) T-150
This tank is more of a replacement for the old kv-1s, it trades alpha (300 vs 390) and speed for armor and some dpm, this tank is more usefull for brawling situations than an m6.
4) KV-2
It’s a good tank finisher, this tank is slow and inaccurate, the derp can be unreliable but useful in some instances, the tank also suffers from poor all around armor.
Mediums
1) Cromwell
An excellent tank, very flexible, good speed, and a fast firing accurate gun. This tank is an excellent support/ flanker tank which can adapt to many different maps
2) M4A3E8
The Easy 8 can be useful with its semi decent gun and mobility, it does have a good turret and gun depression however you should prefer using cromwells to this, due to it’s better ability to do multi-role play.
3) A43
Fast tank with ok armor, basically a lighter armed but more mobile T-34-85. It can very easily get around and it out dpms cromwells.
4) Type 58
It’s a T-34-85 with a worse turret armor profile, and less gun depression. However it does have a little more hp and much better dpm which makes it a more preferable tank.
5) T-34/85
A good all rounder, decent gun and turret, but suffers from poorish gun depression and lacks the speed that a cromwell can do.
Light tanks
There are 2 tanks in #1
1) Type 64 (Premium Tank)
An excellent LT featuring good mobility and a beafed up M1A2 AT gun. This tank has been one of the more reliable tanks in our fleet, it has very decent gun depression and can use that to its advantage when it gets into odd places.
1) T37
This tank is incredible in most areas it has most of the same benefits that the Type 64 has. It is like a slightly buffed version of the old chaffee, in staight line speed and hp; however it isba little worse at circiling, but regardless it is a good tank.
2) VK 28.01
The one real deawback to this tank is its size, however it still can get around. It also uses the 10.5cm derp gun which will full he pen hellcats for 410 damage. Its a fun random tank, but at times very inconsistent.
3) T21
Only really should be used if you are short pressed for scouts, it can do most of what the T37 and Type 64 can do, but it is a bit bigger and clumsier.
Tank Destroyers
1) M18 Hellcat
This is a very flexible TD, it has excellent speed and a mean 90mm gun, it can easily relocate to help where it is needed. Even after the nerf this tank is alright it can still race to forward positions, just be more passive in them and they should be fine.
2) SU-100Y (Premium Tank)
This tank is a huge box with HP, it is mobile and packs a nasty 130mm gun which when loader with gold deals a whopping 510dmg. It can be a useful assault gun however it is not very flexible in rolls.
3) M36 Jackson
Really only should be used as a filler for the hellcat, it has most of the same features its just a lot slower
4) SU-100 (W/ 122mm gun)
Can be useful as a filler for an SU-100Y, it has nasty alpha (390) still but a much better rate of fire, and is a smaller target.
Heavies you don’t want
1) TOG II*(Premium Tank)
It’s big, it’s slow, it’s ugly, it cant go anywhere and is thus useless dead weight
2) Churchill VII
Too slow, not a very threatening gun, armor is only ok
3) VK 36.01(H)
No armor, not the best gun choices, is outclassed by the M6
Mediums you don’t want
1) M4A3E2
This thing is not very fast because of it’s armor which is useless anyways against fleets of real heavy tanks
2) Any German medium, they are big and not that fast with not any real superb guns besides the L/70, but the fact still remains; Cromwell Master Race
Light Tanks You Don’t Want
1) 59-16
Just an all rounder bad tank, out classed by everything else
2) MT-25
A big fat ugly crappier version of the T-50-2, not useful
Tank Destroyers You Don’t Want
1) ARL V39
Its bad don’t bother, no armor, not fast, ugly.
2) AT8
It’s got easy to hit weakspots, it’s slow, and it’s gun isn’t that good
3) Churchill GC
Big, slow, ugly, very weak, not a good TD for these fast paced games.
4) Jagdpanzer IV
If you want a high ROF 135 alpha gun on a tank, look no further than the Cromwell.
pretty much covered it good advice
