Ok I still don`t understand.
Right now the Maus is impossible to balance (Gajin said so)
It should according to gajin not face any current 6.7 Tanks but it should also not face anything with APDSFS which starts at 8.7. In a 0.7 System the 7.7 BR of the mouse would satisfy both of Gajins demands making balancing more percise and easier as there are less variables from the 6.7 tanks and 8.7 tanks to consider when balancing a 7.7 tank.
Another example. The Leo 1 is 7.3 because it lacks the ability to consistently fight against stabilised MBT´s with access to APDSFS at 8.7 and its mobility is nolonger a strenght at that BR as most tanks are far more mobile. It should however also not meet 6.3 or even 6.7 tanks. As fighting unstabilised tanks is more acceptable to gajin than the other way around it was moved down to 7.3
In a 0.7 system it could go to 7.7 and would not face any 6.7 tanks and also not the 8.7 fully stabilised APDSFS slingers.
Hence why I argue that 0.7 makes balance easier and more percise. You have essentially removed the need to consider 2 whole BR`s from a calculation and in most cases it is a case of Too weak to go up but to strong to go down which hampers tanks. So by removing one BR up and down from a possible match you also remove this scenario.
Ofc you could then face the same issue againwith a tank being to strong for two down but to weak for two up. In this case further hard Decompression by extending BR´s would be needed.
The 0.7 System is there to avoid the need to move around 300+ tanks like right now at once for just 0.3BR. Only 0.7 BR tanks would need to go up in a 0.7 system for the same result of decompression but avoiding the compression we now face at 8.0 and 9.0 and also it would keep more tanks at similar BR´s to keep lineups a possibility. Sth which a hard BR decompression would not allow. If done to the end most Lineups would consist of 1 vehicle and two vehicles in a single lineup would be rare.
A lineup is 3 (sometimes 2)or more vehicles of the same BR. Having tanks of different BR´s is not a lineup as you are wasting potential of one or all other vehicles in a lineup.
As 0.7 avoids to much moving around more vehicles will stay at the same BR. A hard BR decompression can not achive that by its very nature of having to change the BR of vehicles to facilitate change.
Bad UI design is not a reason to not do sth. UI can be changed.
If Bad Ui would be reason to not do sth then why do we have the BP while not having a working challenge and mission tracker in the game?
The very same thing is what we now call compression and is rampant. And most of those issues are fixed by the 0.7 system and as stated above much less likely to occure.
No you would still have the same number of steps. Why does an entire BR just vanish in your opinion? A 7.0 tank can still go 7.3, 7.7 or 8.0. Not a single step would be missing. I fail to understand where your misisng step argument comes from. A 0.3 increase in BR is right now a bigger stepp than it would be in 0.7 system. Making the current system again less accurate.
If my tank goes from 7.0 to 7.3 it will now face APDSFS while also facing WWII vehicles. in a 0.7 world it would at 7.3 face only the lates WWII tanks and no APDSFS.
Removing variables makes balance easier and more percise. It is harder to balance 400weights of which 80% have different weights to all others then it is to balance 300 weights of which 50% chare a similar or identical weight.
