Tanks and tiers: balance

[Vomitus]

Allow me to add some points.
If your want to stick to your "linear vision" as a structural vision, you probably want to see it as "logarithmic vision" rather than linear. Examining this concept in one of the aspects, for ex. price, you will understand that difference in 1k for 1-tire tanks is nearly the same for 6k difference for 4-tier tanks. Same applies(should apply!) to all other aspects of "structural tiering/view".
Continuing this thought, it would be necessary to introduce an abstract parameter for every tank which would describe overall toughness, efficiency and usefullness of each tank. It sould be an integral value, that is based on tank price, tank HP, skill damage, skill specials etc. I don't say it would be easy.
And, as for "logarithmic vision", this "toughness parameter" should be the base on which tiers should be built.
Concerning "chaos vision" I find it more appropriate and logical in general, but it's advantages only apply to general concept of tank fleet structure. Dividing tanks to classes as "supporter", "tank", "damage dealer", something else, maybe "air" (I dunno here) you will eventually face a problem of balance where a strictly structured approach will strongly apply.

You can only imagine the look on their face when they know they are destined to die a slow and painful death.
