Savage tiers would die so much faster and subs dropped so much quicker without fflogs there to provide metacontent after the fact. If we, of course, assume that in lieu of FFLogs there'd be nothing, speedkilling and parse running communities wouldn't exist; people would have little reason to pug with strangers outside of their inner circle to improve their personal performance in their off time.

Midare has the right of it imo. There's nuance. No tool brings strictly good things as tools are what the community does with them.
