Summarise a Video Game's Patch Notes Into What Actually Changed

The patch notes are three pages long and most of it does not apply to how you actually play. This sorts the changes into what affects your usual build, general balance changes that pass you by, and bug fixes to ignore, ending with a straight answer on whether relearning anything is worth it.

Summarise these patch notes so I understand what actually changed for how I play: {PATCH_NOTES}. Separate the changes into three groups: things that affect my usual playstyle or build, general balance changes that do not affect me directly, and bug fixes or minor changes I can ignore. End with one line on whether this patch is worth relearning anything for.
