As noted, Battle College is a wiki. I've made some contributions myself, improving some of the pages, but I don't play every faction or ever unit in my factions. The wiki needs people who do use those units need to join up and write what is good about them for any change to come about. If you've had different experiences or unique combos to mention, go put them up.
As others have noted, it's not the place to go to find out the wording of rules, but it gives a general idea of capabilities, and lists what rules the models do have.
