Trying to play without addons
For those who started playing 20 years ago, that interface was the norm.
Player and target frames in the top left, buffs and debuffs in the top right and to see the debuffs applied to the target, sometimes a magnifying glass was needed as the icons were small.
I don't know how it is possible that an interface organized in that way was good for the developers.
And in the end it took them 20 years to understand that it had to be totally reorganized.
Have you ever tried to go back to playing with the 2004 game interface, without the use of addons?
