Honestly if you’ve got issues with balance either post about them on github or make a PR request (most balance things are just JSON, so for the most part you don’t even need to be a coder to do it). At that point people will discuss your changes and, should it be agreed they are valid, they will go in. If there’s problems with balance it’s only very rarely linked to new features (in which case they have to go in before being able to be perfectly balanced anyways, we only have so much testing capabilities), and is much more often linked to people simply not making their issues known strongly or putting up requests to change them.
