Gaijin needed to get rid of their byzantine and moronic BR system years ago. It hamstrings attempts at balance (as if gaijin actually tries to balance). Really the whole leadership of gaijin need to be replaced with people that are at least only moderately incompetent.
The statement doesn’t imply other BRs outside of what 9.3’s compression impacts.
Spall liner means nothing to the skill level at top BR. Spall liners just make bad shots more bad. Spall liner has protected a total of zero tanks I’ve shot at, because spall liners can’t protect crew and ammo.
The 2A5 and 2A7V are effectively the same at top BR.
And yeah, the 2A5 weighs 5 tons less as well while going 9kph faster.
