Thats two. The actual list is a LOT larger. But you know that already. Quartz, Exosus, Details,Recount, Skada, Healbot, Bartender, Bagnon, Threat plates, ELVUI..want me to go on? You know full well that WOW uses a gigantic list of addons, and the average player has a MINIMUM of fifteen loaded.
Dont be disingenous...it doesnt suit you.
And you know this...how?
Given the constant drain of players WOW is experiencing, you have that reversed. I dont miss WOW at all, never will. A lot of people dont these days. Their highest player count was from China...and you know how that ended.
If I did no content, how did I get all my classes to 90, how did I max out my crafters, how did I get my hands on Abyssos and Pandaemonium gearsets......



( Or is this your own narrow view that "content refers to ONLY Savage and Extreme" etc and anything else doesnt matter?....? )
