Agreed on Macros and Addons. Why?
For Macros:
There are way too many spells to just be used without some consolidation. I don't understand why people are so against macros and Addons. If you don't like them, find people who don't like them and stick with them. I for one would love to be able to Bind my Cooldown with a trinket Proc (or whatever the equal in this game is...only lvl 22). Macros make life easier. If they are limited like they are in WoW, they will be fine without being overpowered. You can make them do a lot without them doing everything.
Addons:
We need a combat log and something along the lines of Skada/Recount. People who are "OMG Link Metersss" need not apply for these mods because they are much more useful beyond Epeen competitions. With a damage meter, I can make sure everyone is carrying their weight because Recount and Skada both have functionality beyond damage and DPS They have healing done, healing Taken, Interrupts, etc. I can tell a lot by looking at those little charts and as a Raid Leader, this is information I need to know to make sure my group is all pulling their weight.
Another thing we need are UI customizations. I hate the current UI and I don't see myself liking it anytime soon. I hate it more than Vanilla WoW's Default UI. This game needs addons like xperl, Grid, and Bartender to make things a little more streamlined and less cluttered. Right now, the UI seems so haphazardly put together. If I move the Chat box anywhere, its going to be on top of something else.
We also need some QoL things like Auctioneer. Gatherer doesn't really seem needed in this game but a way to make buffs and debuffs much more noticeable on both the player and the target would be nice. Something with the fuctionality of Tidy Plates would be great too. I could also see a limited Threat Meter doing good for the game.
Addons are an asset and are expected in the Modern MMO. Right now we don't even have a combat log.
