Same goes for almost every single class. Especially the 61+ skills. Didn't know I got a new rank of Shadowbolt at level 62. Nor did my Hunter know that he got Steady Shot at level 62, or 63, don't remember what level it was. It's not on the list.
If I remember correctly, the lists are generated from information uploaded or something like that, right? Which is why you had the old Mangle listed under Druid abilities back in the days even though it never made it through to the very first beta.
Anyways, Azuarc, I think, talked about reviewing them when he updated the class descriptions. This was before the expansion though, I think.
On that note, could you put a direct link to skills/abilities on the main page of the class forum? It's okay if you have to click the link to make the description pop up, but it would be nice with a direct link to the class' skills/abilities lists.
Just, you know, to speed things up. I often go to check on what new things I'll get and having to click all those links, etc. Yeah, I'm lazy.
