If you have yet to explore every map's placeholders, reach all of the usual "unreachable" maps (Emerald Dream/Azshara's Crater/etc...) on live servers via terrain swap, then development is definitely not for you.
-----------------------------------------------
A few basic steps are required to venture around the map without annoying crashes, and some optional ones for unlimited/more eye candy explorations. Requirement are simple logic, basic knowledge about how maps work/load (found all around the forum) and common sense.
