IS-7 8.0 armor update

We are dumbfounded. I admit, I was a bit worried about the IS-7 in 8.0. A nearly unstoppable sloped armor monster roamed in my vision. When we faced it on the test server, the results were shocking but in a different way. Now, either we are that dumb and  we had screwed up the previous tests that much, or Wargaming messed with the armor parameters without any transparency, again. No problem, that’s why we have tests for.

One tiny step forward, one big step back

What did we expect? An impregnable glacis armor and a tougher than ever lower front plate, wider angling options. But unlike American heavies we had tested, this tank seemed to not get the memo about the sloped armor compensation nerf, because we found the upper hull armor of the IS-7 not much different from the previous incarnations. It’s tough all right. The head-on optimised pike nose can be still penetrated casually by Tier X tank destroyer guns. Yeah, but this hasn’t got any news value. We have spotted a difference though. Russian tank hulls lose effective armor for the facing side of the pike nose when angled. This is still true.

However, this loss was reduced a bit in 8.0, sub-240 average penetration guns have very little if any chance to pierce this armor at any range and angle.

So far so good. We had expected a bit more than that, but that’s an improvement nevertheless. However, the disappointments did not end here. For the sake of order, I started to do some re-checking shots at the lower front plate of the IS-7, and this was the point where my jaws dropped. About 10 percent of the former armor was gone. One should expect somehow improved efficiency for a nicely sloped armor plate from the compensation nerf but nothing like that.

In fact, the LFP performed even poorer than in 7.2, when we had made the original IS-7 tests of ours. No improvement, not the same level, it was downgraded.

Randomgoddess is a heartless bitch or…?

The results were so bad that we repeated the LFP tests three times, then we switched back to live servers to find out if we had been mistaken that much before.  And it doesn’t seem like the case, the 7.5 version still behaved as it was supposed to be.

T110E5 8.0 armor update

Back to basics. The Tier X American heavy was the very first tank we had written about like five months ago. In this review, we focus on the changes coming in the next patch. I won’t talk and write much in this post, the tone meant to be more military-like. All Tier X armor protection schemes are going to be revised sooner or later. All right, let’s see the T110E5!  You can use the hull part for the T110E4 too.

Retained characteristics of the T110E5 in patch 8.0

  • The T110E5 is relatively small and mobile for a heavy tank. It’s a light-weight compromise design which concentrates its armor on the front. The frontal armor has mixed zones of especially strong and weaker parts. It’s very hard to use its armor strengths, because there is always a con for a pro.
  • Mobility is at least as important part of the protection as the armor itself
  • Angling of the egg-shaped hull is possible, although it’s not recommended against every opponent and in every situation. See details later.
  • There are three main vulnerable zones we should focus on: the lower front plate, the commanders cupola and the hull sides.

Armor changes in general for 8.0

  • The sloped parts of front armor are now stronger by a rough 10 percent
  • The upper front plate or glacis now gives reliable protection against all Tier X tank guns. Only Tier X TD guns has considerable chance to penetrate it.
  • The lower front plate and the cupola got a very bit tougher.
  • Against non-overmatching (at least by a factor of two) projectiles with 200+ avg pen the hull side armor allows angling up to 25 degrees. Sub-200 avg pen guns allow angling for the sides up to 30-35 degrees. Approaching an opponent behind a corner is less risky for the sides (and for the ammo rack behind them) now.
  • Weak spots against AP and HEAT (gold ammo) are most similar.

Effective armor changes for 8.0 – Tier VII

Today, we start the 8.0 conversion. I’ve chosen tanks and TDs with considerable amount of slope and converted their effective armor to 8.0 standard. Although the new version of World of Tanks is not live yet, we would like to help with these tables upfront. Tier after Tier will be uploaded in the next few days, but Tier X armor is going to be re-tested completely. The first table is about Tier VII, and I try to read out some changes in the metagame.

What you should know when you read this table

  1. All numbers are calculated, but they correspond with gameplay experience and previous test results. Basically, effective armor thickness is the same as we call WoT-equivalent armor, an armor value a gun with the same average penetration has 50 percent chance to defeat at short-range without side angle. Our “seven shot protection numbers” are usually lower than these by 10-15 percent.
  2. The average compensation for AP against sloped armor is 8 degrees at this time (confirmed by Storm in 7.3), this will be halved in 8.0.
  3. The game calculates overmatch-effect more than one way. If a gun has double the average penetration than the nominal thickness of the armor, the current compensation will increase to 10 degrees, probably less in the upcoming version. However, this difference is minor.
  4. It’s recommended to multiply the WoT-equivalent armor values by 1.2 to measure if your gun is up to that particular target and armor plate.
  5. 40-45 degrees side angle means about extra 1.25X multiplier for effective armor, although at such high angles thin sides (80 mm and below)  usually become vulnerable in Tier VII.
