In WoW Classic, players use addons to create customized gameplay, and these customizations include action bars, raid frames, graphic overlays, along with rotation reminder spells, boss warning, and tracking of buffs & de-buffs. There are a few highly recommended addons for Warrior DPS that plays a huge role in helping during combat, as well as provide a playful experience during the journey.
Swing Timer
This add-on was designed to track your weapons swing time during combat. It is highly important because every weapon has a different swing time, and it’s hard to identify the speed unless you’re using this privilege. It helps to predict your rage generation and is said to be essential while levelling up, or during PVP (Player VS Player) to use the spell Hamstring and kite against 
enemies. It opens up opportunities for Warrior DPS class, regarding their positioning and ability usage. Thus, proves to be a useful addon throughout the gameplay.
Gear Swapping
This add-on was designed for you to save different sets of equipment’s and quickly swap into them by assigning them to a key. Warriors have many sets in their inventory, which needs to be swapped during various pulls. So, rather than consuming time and changing into a different set of gear the hard way, using this addon can be very useful, as all it requires is a tap on a 
single key. This addon can also be designed according to the user’s choice, for example, the gear should switch when you wield a sword or trinkets to be switched when the cooldown is required etc. You can customize it in any way possible to bring out the most of this add-on.
Aura Tracking
This add-on was designed to track various buffs and de-buffs, based on how efficiently you can use the resources that you hold. In other words, you spend your rage depending on the time you have to wait for a proc to be accessible, but you don’t know the right time for it. Therefore, this addon helps you track the time, and lets you maximize the full potential of your class. It can be used to track anything in terms of PVE and PVP.
Action Bar: Stance-Friendly
Before you download the addon, do make use that it’s compatible with your legacy Warrior feature. This addon was designed based on the Warrior class unique abilities and stances because binding each ability separately would take up a lot of effort and you may end up with several extra bind. So, with the help of this addon, you’ll be able to customize your action bar, while considering your gameplay and comfort level.
