combat damage formula

[Furniture]

Hey, I very badly would like to start work on a classic server, but I'm aware from reading various old posts that the current combat damage formula only works right at higher levels, as the high end raids were what was used to test the formulas. This makes it so the mid to low end game players without insane gear takes much more damage than they should if they have good gear, as AC has less of an effect so the AC values so only the high end gear really has an impact on the damage you take.

I understand that there is no catch all formula code that was written to account for all levels, but I'm trying to figure out how I can modify my code to work more realistically for older content. If anyone has any ideas on a quick fix (can be sloppy) that i can do to my code to make AC work better it would be much appreciated
