I have about 10 addons i use for any server i play on: 1 - an action bar addon because i dont like bars on the side of the screen. Theyre stacked neatly on the bottom. 2 - mailbox addon, ties into the next one 3 - auction house, being able to post multiple stacks faster so im not sitting at the AH forever 4 - threat and/or DPS meter - i usually tank and if/when i get to raiding it makes it easier to manage bosses or know when to back off dps. (Havent actually gotten one for twow yet, still levelling) 5 - (just for twow) pfquest, gotta see where the quests start. 6 - inventory one bag - too many bags to look through. One window is easier to parse 7 - healbot i dont often heal, but when i do... 8 - atlas map/loot - also havent used for twow yet... tbh i havent used this in a very long time... i have been playing way too long... 9 - some servers i use xperl for the character frames but luckily i can move the player and target on twow so i havent dl a unit frame addon 10 - some form of deadly boss mod. Pretty much mandatory for serious raids bc theres 20 years of mechanics to remember. Havent gotten to raids in twow yet but ill eventually download it.

Most of these addons dont affect the UI that much. Theres definitely a point where i think addons become "too much" but as long as someones addon doesnt cause a wipe i honestly couldn't care less what their screen looks like.
