I'm not sure if this is by design or not but it would be great to have the option to directly attack (revenge) a person on the "History" tab. Similar to players who've attacked you in the news feed, we have the option to "Invade" that player for an attack.

Currently, it is very difficult to find someone you're having a chain with by refreshing the Vengence page multiple times.

This could save a lot of overhead from your servers and save us a lot of time as well.
