It depends if the change is a nerf, buff, or overhaul, and whether the change is universal or localized.

As long as the patch is a buff (like bosco's damage/mining) or a localized change (flamer nerf) then things should be okay.

Obviously "localized" is subjective and even though something like Sandblasted is just one biome in the game, if all the WR from Sandblasted couldn't be beaten in any other biome, and Sandblasted gets nerfed, then that's pretty universal

It's not something you can template, it will need to be considered on a case by case basis
