Warcraft editor is easy to understand if you learned that editor before sc, after any of these programming skills ex. VB8, C, or anything higher or as advanced than these.
The reason that people from the starcraft editor find the wc3 editor so complicated is because there not used to it. Sc=Order unit to here wc=many other things. This is because if Wc was like this then it would have an insane amount of these. But because i learned wc3 first i find sc frustrating because i am limited in my creative thinking. I only map sc because i like to give people who still play the game better things(soon sc will be out and wc3 will live for at least 5 more years because of its 3d capabilities[sc will die faster if sc2 comes out]). Technically the sc2 editor cannot be better than the wc3 editor, except by including tools for things like model creating and a good jass editor. Also make it faster and more stable(i dont know how they could make it more stable) Enless a brand new code comes out that introduces a 4d then it wont be an extreme step. People are dreaming if the sc editor will have limits that can be reached. SC2 editor may have better capabilities as graphics improve along with things to make these playable on most systems(high poly models and other things will make the game lag like crazy(was smart to put in this form tho because of future computers[can handle the lag]) so the Graphics won't get much better for another few years due to lag problems.
