The inventory system in World of Warcraft is kind of a mess for the basic version

Details! Damage Meter is a highly accurate visual DPS indicator that lets you know the amount of damage you as well as all your players are doing through the combat log. If you're playing a game with a damage-dealing specific game, I'm going to emphasize the importance of making sure you have details. While it will help you up your game and make WOW WoTLK Classic Gold  you more efficient, but the additional tools available are extremely beneficial, like being able to see the selection of talents and the item level of your party members.

WeakAuras 2

The most complex and complex software on this list. WeakAuras 2 is an application that allows you to display specific graphic elements on the screen to show buffs, debuffs and other important status effects instead of just overwhelming your eyes with amounts and meters. There's an insane level of customization that's available here with everything from making custom sounds (like Owen Wilson saying "Wow!") to class-appropriate visual cues. It's a lot to take in, but meralonne's video guide will help you get started. The good thing with Weak Auras 2 is that it is a great alternative to the time to code your own custom ones It is easy to bring templates in from players. Here's a site that has numerous built-in WeakAuras 2 scripts you could use.

MoveAnything

It's easy to guess the function of this add-on. MoveAnything is an extremely effective tool which lets you alter each UI element providing you with complete control over not only your action bars , but also your quest list and portrait locations, minimap's location and more. If you've ever wanted to overhaul the entire UI of WoW It's a good starting point.

ElvUI

This is one of the most popular total conversion addons for World of Warcraft. ElvUI replaces every single user interface component with a modern design that's more modern and readable. The drawback, of course, is that you're also eliminating the fantasy-themed UI completely. It's been a tradition to install and update ElvUI manually. Although it's not a huge amount of a chore it's becoming increasingly difficult. Fortunately, there are a variety of more modern addon managers popping up that let you update it along with your other add-ons. If you do decide to use manual updates to update it, the benefits ElvUI offers will make the cost more than worth it.

One of the things I love that I love about ElvUI is the fact that it has an in-game setup process that'll assist in customizing the UI according to your requirements. There are specific setups for each class that focus on the elements of the interface that are most relevant to your job and the settings offer many options to explore. I especially love how action  WoTLK Classic Gold bars function within ElvUI, and its built-in add-ons mean you don't need to juggle other addons like OmniCC. Beware of this, if would like to utilize ElvUI make sure you install it before bringing additional addons into the fold because it doesn't always function well.
