No you're wrong about relic not permitting changes because they adjusted bolster last patch, they locked it behind T1 but lets be honest that's hardly solving anything.
These are suggestions to stuff that could be tested out, then you could make bolster an upgrade option to counter stuff like sniper cheese. While also toning down other issues with the upgrade to achieve any small fixes where they are oppressive.
Either way I don't see how adjusting bolster isn't preferable to nerfing and reverting nerfs to 4man sections for years on end. It's been 4 years and it's clearly not worked, I think there was a fake Einstein qoute about that or something.
