Before BlizzCon, I left off with the beginnings of how to put together your UI. While it would be easy to generate a post of macros and Weak Auras import strings, that wasn't my intent. User interfaces in WoW are varied and can be unique to the player, so I think it's a greater lesson to learn how you can design your UI to help you, rather than to help patchwork import settings together for you.
So while the setup of unit frames may have seemed incredibly basic to some readers, knowing where some set frames are helps you take control of how your targets are presented to you. Much like healers considering a raid frames grid to be a central part of a healing UI, having damage targets at the ready is a central if often subconscious part of a DPS UI. Today is another basic topic, but it too has a subtle effect on how a proper UI setup can aid in DPS.
