Hunter99 is well known for his unique insights into the nature of things.
Case in point:
Fourth, remove Gods and God granted powers. Have only one type of magic with different branches of specialization such as healing, war etc. Remove the necessity for any sort of religious faith for the using a certain type of magic. Make magic in this regard similar to science with scientific laws behind it, not dependent on the whims of a deity.
In juxtaposition with this:
Seventh, and this is purely aesthetic, remove all racially ugly rational animals such as trolls, goblins etc. and some non-rational animals which are ugly by virtue of belonging to a particular species. The reason for this is because I don’t believe that God (to use a figure of speech, even though I don‘t believe in God), or Tao, or the Logos could create anything so ugly as trolls and goblins etc.
To sum those two up: get rid of the ugly species because the gods of the D&D universe wouldn't have created them...if they existed. But they don't because we deleted them too.
