I think the basic problem is that you are using a prerendered image
which is designed for viewing on a screen.  The scale determines both
font sizes and what is shown or not shown, and the text is pre-rendered
in the tiles.

What you want, I think, is a higher-resolution generation of tiles,
rather than to increase the resolution at which you are showing the
tiles.


I would advise that you try to really understand what ArcMap is doing,
and be able to explain what "works" means in a really crisp way.

Perhaps they are using one resolution for the WMS and another for the
rest of the data.
