In a general sense, one could expect Warren Ellis to restore a sense of
the
mystical to the series.  Quinn's stories were more superhero-oriented;
the issues of DR. STRANGE featuring Polaris and the Hulk, if merely
padding
in plotting terms, had better characterization than the "regular" stories
did.
In recent issues, the subplot showing the effects of the War on Dormammu's
dimension has been a mistake, I think, because it turns the "Dark
Dimension"
into another run-of-the-mill fantasy setting with less mysticism--even
if Quinn and Skolnick were more comfortable with that approach.

One might also expect Ellis to show more attention to detail and depth in
his characterization.  Quinn's Salome was much more of a plot device to
get
"elemental magick" into the series than a serious opponent.  There was a
severe lack of motivation and character background.  As for detail:  Well,
to cite two examples:  Quinn continued to have Strange use the Orb of
Agamotto
when he shouldn't have even had it, much less been able to use it; Quinn
also
gave Dormammu a physical body when it had been established years ago that
Dormammu's body was pure flame.  It's possible to go into more detail on
Quinn's plotting/characterization weaknesses (I have in other venues) but
there would be little point to that now.
