Archon, the company behind Warcraft Logs, has released its new website, which has been updated with some really useful tools for Cataclysm Classic raiders.
Archon for Cataclysm Classic
First are the tier lists, which are based on data from the last fourteen days. Here you can view by either Popularity or Throughput to find out which specs are in each tier using the common S-C ranking system.
This isn't just DPS, you can also easily swap to a healer or tank view and choose your raid size.
Also, currently available in Beta, Archon can show which gear choices are being made by players of a chosen class or spec.
While this lacks some context around the gear choices being made, this is a brilliant way to view the current meta-gearing choices.
