yep, i think also there should be a category.
I (the one who mainly written the ftl-wiki-entry) wasn't realy sure were to put it, because its not realy pure addon/macro related, so I personally would support a category like 'targeting approaches' or something similar...

...systems which come in mind to post there, would be :

simple 'fixed' leader:
  • assist based
  • focus based
leaderless variants:

perhaps we could examine first which others are out there
