I can only see that I got an achievement, but not what it means
I noticed that when I'm an ally, I can go to my hero's page and there's a menu option to see their achievements, but when I'm on my own hero page, there isn't a menu option to see my achievements and when I click on an achievement earned in my activity stream, nothing happens. I'd like to be able to see what the achievement means on my own hero page.
You can view achievements if you go to your profile (by clicking your username in the upper right).
Edit: finally figured out I can see the achievements from the profile tab by clicking on my icon. I would still like to see the link in Activity work, though.
