Multiplayer games (with encryption)?

So, any special tacts when trying to create hacks for online multiplayer games with some sort of encryption, like bloodline champions (weird that no hacks exists for this game even though it's several years old now)? Some people claim one must be a master of reverse engineering etc to have a chance. But isnt the goal to find static memory adresses to use and abuse? I dont see how reverse engineering would help me in this cause.

Hardly any decent hacks use memory editing and alot more can be accomplished with reverse engineering than with mem editing static addresses
