I would join a custom server,but not any server and maybe classic official. Btw race wars is a very good idea. Every race would reside to its village and maybe there would be something like 3 siegable castles to make the wars more massive. And something like a global market and an arena where ppl from all races can meet each other. As regards the reason that i prefer custom things is that i am really bored of l2 same quests, same grinding ,same things for over 6 years.
