Some things we are able to alter in a live state, which we refer to as 'tweakables' in the studio.
It's an area that we've really made some gains on with Battlefield 2042, working towards that ability to react to things in a much quicker way by altering the values such as the SPH Explosive Launcher, or disabling something that is clearly causing an issue.
Unfortunately, like the Stinger issue, not everything can be as reactive like that and they do require client updates rather than server ones. Not everything has a tweakable too.
But it's something we continue to work towards - and I hope those changes are spotted too! :)
