I think you might have a little problem within your dbc. The first number after the x, y, z axis is a ball shaped area around that point where it will trigger. As you set it to 0.0 it can´t trigger. Try it out with 3.0 or 5.0.

this is what i go when i changed the path to Path = C:Program Files (x86)World of Warcraft 3.3.5aData/
i got this on my log
3 - (Noggit.cpp:130): Noggit Studio - SDL 1.2

Might be a stupid point but:
C:Program Files (x86)World of Warcraft 3.3.5aData/
=!
C:Program Files (x86)World of Warcraft 3.3.5aData

try it with a backslash.

Looks nice Ingame screens?
And all those brown spaces: WIll you overwork or retexture them or shall they stay like this?

Whenever I create a new MPQ and add all my .ADT's , the patch only is about 1.53MB but all those 82 ADT's are about 37MB.

Well this sounds definetly wrong 1,53mb is about the size of one adt. Are you sure that you added all of them? Maybe attach your MPQ so we can have a closer look at it.

For your question concerning common-2.MPQ and patch-4.MPQ. You can somehow manage that noggit also "reads" your own patchs (in the config file or such. Just look up in the noggit Manual or Wiki).

WoW itself always takes the data from the newest patch. By this we can override blizzards content located in common.MPQ until patch-3.MPQ by creating our own patch-4.MPQ. If you modify blizzard´s mpq always make a backup because you could blow up the whole thing

Sounds kinda interesting but do you want to adopt your system within the normal warcraft univers and without own content?
Also does it sound like some kind of skyrim-system where you can finally skill up everything and this way become a high magican wearing plate armor and a two-handed sword. Or do you want to give a certain number of skill points for each level/challange so that p.e. the player has 100 points to spend for 200 skills?

Well those 8 categories shown there should be managed somehow (how they are arranged, where they get the progress from etc.). This is the file/line you have to extend by your category. But i don´t have a single idea where to search... any achievment*.dbc´s for sure :X

Image doesn´t load Nice idea tough.
