Map issues in World of Tanks 0.8.3

I’m an avid player of the MMO World of Tanks where I roam as Hagbardur and have kept a close eye on how the map changes have affected the matches. Following the tremendous work done by Phalynx, where he collects data from players on matches and makes them available on his website, I managed to get together some statistics on team performances in the maps because quite frankly there were some seriously flawed maps.

It was good timing as the day after I finished compiling the percentage chances the developer Overlord posted a topic on maps in WOT. Since my findings could use some visual aid I’ve decided to present them here.

All numbers taken from Phalynxs website with Tanks with over 100 battles included. I’m sure Overlord has access to much accurate numbers but until Wargaming releases them this is the best approximation we can get.

 

The Percentages

Here I list, in order of worst skewed maps to least skewed, the maps, the number of times Team 1 (green) won and Team 2 (red) won. You can see at the bottom of the post which team is Team 1 Green and Team 2 Red. The skew number is the absolute percentage difference between the two teams. I also highlight maps which are prone to draws.

The Worst Performers

Most skewed map

Westfield – Assault

It is no great shock that Westfield – Assault mode is the most skewed map, the defenders have ample sniping spots in the lower right corner and on the other side of the valley very well protected spotting locations that can also shoot at anyone travelling the edges of the map. With the defenders (Green on this map) winning 66% of the battles this needs a major re-balance.

 

Fjords

Fjords

Fjords is skewed towards the Green team which have a 32% edge on the Red. Their protected sniping spots both in the north and south that cover the field in the north no doubt are a big factor for this as well as the natural defense positions they get in the middle and south roads.

 

Malinovka - Assault

Malinovka – Assault

Malinovka in assault mode is skewed 32% towards the Green defenders who not only enjoy higher ground but also can get to ample forest cover faster than the Red attackers. Playing this map as a T95 on the Red attacking team is nothing short of the biggest joke played on players as your lack of speed and lack of cover while attacking mean that if you are not killed by artillery then you are too slow to make a difference in the attack. Other slow tanks on the attacking side suffer heavily from this as well with the Physics update punishing their uphill climbing. This needs better balance and this is why I have personally disabled Assault and Encounter modes on my account.

 

Sand River - Assault

Sand River – Assault

The Green defenders get a 30% advantage against the Red attackers. Crucially the Green team can snipe any Reds trying to go north so those that do make it to the north are badly beaten and pushing them away is quite easy usually. A fast medium rush from Reds to the north can combat this but this is a huge weak spot for the Reds.

 

Dragon Ridge

Dragon Ridge

Dragon Ridge is skewed heavily towards the Green team in the south who are 29% more likely to win each game. First of all they get, from their own spawn, a superb sniping spot to shoot any tanks in the Red team moving from their spawn towards the town in the middle. Secondly from the mountain in front of their spawn they get good sniping lines on the town in the middle, something that the Red team do not get from their own mountain safety. Thirdly the map funnels all the play into the gorge in the east, where Green team have better sniping lines into it both from their spawn and the path in the middle, and into the town where Green are again better positioned. This map is thankfully being removed in 0.8.4 and hopefully will come out of it not only more enjoyable to play but more equal for both teams.

 

Province

Province

Province is a special case as it is mostly played in tier III and lower these days. Here the Green team that start on the left side of the map enjoy 26% more wins than the Red team on the right side of the map.

 

Serene Coast

Serene Coast

Special mention must go to Serene Coast which is undisputed king of Draws, 8% is an incredibly high number but not surprising for those that have played it. Green have a 15% advantage over the Red team, no doubt due to the sniping hill and the B1 corner for spotting. It will be removed in 0.8.4 and hopefully adjusted to make gameplay more smooth.

    Great job on analysis. Was easy to read, and maps made it great!
    Something many of us long suspected, shown elegantly on your page.
    *Thumbs up*

    Wow, a lot of work and some great analysis! Very well written. Hopefully we can get some internal numbers and see how close you are on this. Remember we also have to draw numbers from every regional server cluster, and tactics on each map may vary in different communities, possibly making the percentages a bit different. We will also use heat maps for our internal analysis, which show where players move, shoot, and die over the course of thousands of battles. This helps us spot the best (and worst) places to move and hide, that way when we rework the maps we can fix those issues and make them better for both sides and all kinds of tanks.

    any info on how large is your data pool?

    and is it random battles only or companies/cw included?

      According to http://www.vbaddict.net/wot

      Data for this statistics is based on 664,151 battle results of the last 30 days with
      19.92 Mio tanks participated.

      As for standard or company battle I’m not sure but I would think Company Battles, if included, are a neglible amount.
