I don't think you understand how two-faction games work. There will ALWAYS be a tilt to one side, no matter what. This is why developers started tilting towards warzones. Everyone thinks that world PvP is this grand battle where you stroll onto the battlefield and there are twenty of your guys on one side and equal amounts on the other, that never happens. Even with a 50/50 server, you are going to get a side more PvP inclined and ganking will still be prominent.
The only thing that you can do is add more warzones, and so far I like their direction with it. What I do not like is being forced to go to Ilum for PvP bags and they won't be able to create a fair Ilum unless they make it similar to a warzone. What they should have done is made it a locked capture point type of invasion warzone similar to MoBA style games and Unreal Tournament.
