Well I updated the Influence Hack for Warhammer Online, in theory this hack should continue to work after (minor?) updates. It searches through memory for the influence hack location using a pattern created by IDA.
The pattern matching isn't that exciting, just search for an array of bytes and if the match is found then that's the address that I want. Its reasonably fast (it finds the address in 1.3.4.529 within 1 second on my PC).
Anyhow, you can download it here. Enjoy!
Edit:
According to this post Mythic is apparently detecting influence hacks (finally):

So be careful with using this hack.
