So I actually ran some dungeons with complete base UI. It was fine generally, at least for tanking. Granted I’ve run enough dungeons that I have 0 learning curve occurring.
But I also don’t use many addons.
OmniCD for party CD tracking. Losing it isn’t a big deal, but it would make me more hesistant to bring specs I don’t play with often, or at least specs on different cd timers.
Bigwigs (Going native I believe?)
Details (Going native.)
Simc.
MDT (Should be native.)
Weak Auras.
My weak auras, are my defensives somewhere easier for me to see. This could be replaced by Tellmewhen right now. I haven’t messed with Blizzards cooldown manager, but hopefully it is customizable enough.
Targeted Spells (Going native)
Mouse Coursor, puts a circle around my mouse, makes it easier to see (hopefully it goes native.)
Balance Druid eclipse thing, that just shows remaining itme on eclipse in a easier to see spot, but I’ve only boomkined a few keys.
Bossmod Timeline (Going native as an option I believe.)
Addon’s I have turned off. Premade Group Filter, Notevenclose. I just don’t use them that often. PGF should go native, if it’s not.
WA I used to use, mob% on bar (should go native if it’s not).
So it’s not like I’m actually losing a ton by turning stuff off, but in general for tanking 10-15 keys with the experience I had I felt fine. I’m sure it would be rougher learning new dungeons.
