0.3 or 0.7 would not only break the system which is in many ways designed around 1.0, but also very importantly it’s entirely unintuitive. The actual solution is just to move somethings further apart (though not actually as much as some people like to yell for).
Something else which would help with balancing without affecting compression/matchmaking would be to actually use all decimal points. This would more than triple the nuance that can be applied to balance, especially vehicles that are close-but-different in performance, with no actual downsides. And it’s more intuitive.
It really wouldn’t though, some vehicles would definitely need br adjustments but there is nothing stopping you from having the same lineup as before but with less matchmaking spread.
So what you’re saying is vehicles would be moved from BRs where they’re balanced for the sake of lineups, and you’re in favor of this? You think that’s decompression? To effectively reduce the number of BRs by squishing, literally compressing, vehicles into single-BR lineups?
Part of the problem is Gaijin trying to go for the record of we have the most vehicles than any other game award.
A vast amount of ships/planes and vehicles have no place or point in the game, so they have to balance them to make them playable to some extent. all this does is either moves the problem to somewhere else or creates an unbalanced situation to the advantage or detriment of certain vehicles.
Having the random RNG/ghost shells built into the game can alleviate this but this is done across the board so everybody suffers.
Yes it is nice not to all be using the same thing ( realistically that was a thing though) but the mechanics of the game curtail this a lot and some vehicles are practically unplayable to the point of uselessness.
