I bring to you a TrinityCore2 3.3.5a patch to make all races and all classes, installation is pretty self explanatory its just 2 sql files and a patch.mpq
TC2 arac.rar
To install do the following:
-1: You can either take the CharBaseInfo.dbc and CharStartOutfit.dbc in the DBC folder and pack them into you own mpq or you can use the patch-4.mpq I have provided
-2: Take whichever of the 2 mpq you prefer from step 1 and put them inside "YourWoWRootFolder/Data" there you will find a patch, patch2, patch3 mpq just add that patch4 mpq or whatever mpq you made in step 1
-3: in the sql folder simply run the alliance_all_races and the horde_all_races files while you have some SQL software open (i prefer heidi sql) and it should install them
If those steps dont work feel free to add my skype (in signi) and i can help you out
