I initially considered allowing the specification of relative class-exclusive weapon preferences by ranking, but having that level of control turned out to be both messy, and in my opinion not that useful.

One can see the prototype for the rank-specific preference here in this earlier commit:

It seems easier to just assume that any class-exclusive looting preferences should apply to the LT level, mostly because when I tried to come up with initial configurations I ended up putting most preferences at the LT level anyway.

Also for reference, since I needed to consider whether selections would have been redundant and already possible with #1800, these are the weapons that each class can never select even if they were LT rank:

Recon:

  • ZR suppressed
  • MX
  • MX suppressed
  • SRS
  • AA13

Assault:

  • SRM suppressed
  • Jitte suppressed
  • ZR68 scoped
  • PZ

Support:

  • SRM suppressed
  • Jitte suppresed
  • ZR suppressed
  • ZR scoped
  • SRS
  • AA13

For testing, the permutations are kind of tricky, but a basic test is to set all bots to Recon with bot_class 0, spawn as an Assault with a ZR suppressed, and throw it at a friendly recon bot. Before with #1800 the bots would not consider the swap.
