So you're saying that showing dots on nameplates (something blizz ui doesn't do) makes someone a baddie? Or how about a weak aura for important debuffs so you're not having to constantly check the top right corner of your screen whilst focusing on the job t hand?
I'm very doubtful you raid without any add ons yourself.
Oh and the word baddie just makes you look like an ass.
On topic I use about 5-10 add ons for raiding. Although one of them is elv ui which does what many custom uis require alot of add ons to do.
