So today I am going to talk aout the best Mod I have found out there for unit frames. On my mage (my main) I currently use pitbull for all my unit frame needs. The thing that is most amazing about pitbull, is it's amount of customization. Pitbull is configured via the use of layouts, you then apply these layouts to the different units. This is nice, because I am able to use the same layout for my target as I use for my player. Pitbull can be configured to show as much or as little information as you want. For my mage, I have two settings, one for PVP and one for PVE.
My PVE set up is designed to show me all the information I need to know about my party/raid, as well as knowing what percent the boss is at. Not a ton of information needed here, so I made it flashy and fun. On the other hand, my PVP set up for pitbull is very streamlined. it is what you see on my screenshots. It shows (in a very large lettering) my health and mana, that's it, for me everything else is just excess that I do not need on my unit frames. I use other addons for vital information, that way my information is not crowded into a small unit frame. With both my set ups, I have my unit frame and my target frame in the middle bottom of my UI, it makes it so my eyes don't have to do much moving, and helps me avoid tunnel vision when fighting.
What addon do you use for unit frames? do you use the default frame? How are your unit frames configured? What was your thought process when you set your unit frames up?
