Terrible usability, and certain stats/fields lead directly into a spreadsheet of game ripped stats.
Though that's really to be expected, since it's community-created, and the community has no obligation to devote proper effort and time to it.
A developer should always create a proper wiki with good readability/usability for a competitive multiplayer game, especially one with such relatively intricate systems as CoH2 (compared to, say, something like a hitscan FPS).
You seem real dedicated to shitting on Relic with your new coh2.org account it's pretty funny. your raging in the "have Relic abandoned the game" thread detracts from anything you have to say in this thread.
Anyway, Relic never made a wiki w/ coh1. It sure would be helpful. There was this:
http://www.coh2-stats.com/
There was also a Google Doc that had all damage related stats for all four factions (prior to UKF). Weapon cooldown, reload time/frequency, weapon wind-up time, etc., so you could really see what stats were affecting dps.
If you'd like to see some coh2 stats you're more than welcome to extract the files, make your own website, and upload the data in a streamlined, accurate, and in-depth way!
Edit: I found the spreadsheet, no idea when it was last updated though:

If you really care about the stats you can probably look at the changelog for a particular unit and see if any changes have been made.
