Half of the joy of playing Path of Exile is coming with your own build. Sure, you can try to copy someone else one but between gear, gems, passive tree and your own skills as a gamer, the same "build" may simply not work for you.

My 1st character was a minion master and while it kind of worked I found the build too slow and passive for my tastes.

Path of Exile is like playing with Legos, it's about building and testing, looking for that last piece to finish your masterpiece and sometimes rebuilding from scratch.
