Addons are huge. Better ui, customizable everything, market/auction house helpers, etc. Tons of small stuff just to make life easier but hey that's what they're for.
Best Addons (imo):
LUI (UI, player frames)
Combat Metrics (DPS chart) Combat Cloud (Floating numbers)
Skyshards (shows all skyshards on map)
Lorebooks (shows all lorebooks on map)
Tamriel Trade Centre (Auction house listings) Master Merchant (Auction house actual sales) These two compliment each other really well.
Awesome Guild Stores (Gives you a lot more options to specify when buying items from guild stores)
Wykkyd Outfitter (Outdated atm but still works. This allows you to switch item sets and builds with a single click, like Armory for D3)
