The current TBC client have a level 1 pointer and is ez-mode to find.
However possibly due to restructuring or code-cleanup the WotLK this have changed.
I have heard many people whining over the playerbase's new repoint system in 3.0.1.8334 and how it is "100% variable" etc.
So enstead of spending my evning with my GF infront of the TV i took some time off to crack the new offsets. I rewrote one of my olf reverse scripts to find the playerbase.
The results was 3 Working Level 6 Pointers.
There might be more but as you can see i did set some limitations to the backtracing but 3 is more than enought to get some stuff up and going. It works perfectly with WoWInfinity
