Same script, doing the same thing, being run by multiple characters. Right now each flows through the script independently, each creating their own ignore lists, but some of their actions are redundant since the other character has already done it.
example: idoc, 2 characters looting, no need for both to check every item. If character A finds a sword but its not legendary or special and he ignores it there's no need to character B to waste time on it. A shared ignore list would help where milliseconds count.
example two: resource collection(tree stump logs, dolphin rug SoS's etc). Finishing the job fast with two characters would be easier if the characters walked towards uncollected goods only, without checking things the other already has.
I'd have some use with my tailor/smith in sharing the work area too while making full suits (lrc, 70's etc). I have no clue how much is too much for the registry to handle. I've started my scripts slow and revised them to speed them up until I am happy and they feel solid.
