You could get away with reducing both the number of visible bars in your threat meter and the number of debuffs over your target frame to improve visibility. From what I can tell there isn't any particular reason to show that much information and it seems unnecessary.
Also Lalaine IM GOING TO TELL BAGELS YOU DONT USE RAID FRAMES.
DeeUi is a medium weight verry customizable addon compilation meant to improve look of old blizzard Ui by much and ofc your Gameplay when it comes to raiding mainly. Fits best to PVE but works verry fine in PVP also.
Atm this compilation is seted up for 2 classes Mage and Druid(Tank/healer) If you play any other class you will prolly need to change a few colors (for a class look) and setup your Vuhdo addon for healers.
Damn casuals and their vending machines. Back in my day, We had to go all the way from Orgrimmar to Desolace to pick up chips from the store. we had to do an extensive attunement quest to get into the store and we had to assemble 39 other people to fight the many other trash mobs, i mean trash food, to get to the chip isle. Oh and most of us couldn't even afford our epic car mount to drive there, we had to settle for our 60% bike mounts.
Would you be kind enough to help me set up my LUI like yours. Cause I tried finding every addon you used in your post for Mage's UI and I think I am missing a bunch to make it complete. I can uploaded your screenshots marked with red circles to where what addons I have concerns about. Please help me and make this happen. I can also link with url all the screenshots including my LUI at the moment.
