Yes we have and not it not "just entirely my own opinion and nobody else's" as I have clearly proven.
And once more I have to ask you, without a benchmark how do you know if a unit is UP or OP?
All you have clearly proved is the fact that you're clinging to a balance principal of a balance developer who doesn't work at relic for half a decade now.
Stop saying how it was great when everyone used oil lamps and rode on horses, get on times and accept electricity, cars and replacement of that old balance philosophy you're clinging to so hard.
With old balance philosophy, Tiger should LOSE to 2 shermans attacking it frontally every single time.
And how do you tell if a unit is op?
By extreme meta changes that favor no variety over that single unit(if faction design allows for such flexibility, USF and OKW didn't had much of a choice previously with rifle and volk spam, so cost effectiveness measured around other infantries was the indicator here and nerfs were) and that single units performance measured against its role equivalents with adjustments for possible price differences.
tl;dr a lot of changed and a lot of factors needs to be taken into account, "benchmark balancing" is dead with PQ leaving Relic, relative balancing is the approach modders took ever since they took over and they are doing much better job so far imo without famous relic penta nerfs/buffs.
