Arena Rankings - http://www.arenajunkies.com/rankings/
This is step one of having the most comprehensive rankings comparison tools available. Basically it lets you browse top teams from across all regions and see their comps, who the active players are, etc. Now this exists on plenty of sites before, but we have made it even better.
1) Sort by class composition. Curious what the top Warrior/Druid teams are? How about what are the popular 3v3 teams that have both a mage and a druid on them. You can sort by classes and see what teams come up.
2) We also do real time talent spec display. Always wondered what the top warlocks run on a mage/lock/rogue 3v3 team? We will show you the specs based on whatever filter you have chosen.
Now, as always, the armory is still bugging a little bit, so we will be working on fixing things up as we can. Expect things to stabilize a bit and get working better as we finally get it tested. If you have any feedback on the tool, please let us know in the Site Feedback Forum..
