Every single WOW player was a beginner when he/she started playing. However, as time passes, experience is higher and fewer mistakes are made.
When you are a beginner and you want to improve how well you play the game, you need to be aware of the mistakes you might make without even realizing it. By the time you reach a World Of Warcraft raid, you need to be ready. This is why you absolutely need to avoid the following very common WOW mistakes made by beginners.
Clicking
Excessive clicking is the number one sign that you are a beginner in WOW. This is because when the mouse is used to click the spells, reaction times are drastically reduced. You need to get used to utilizing keybindings. Map the spells to the keyboard or utilize a good MMO mouse. At first glance, this does not seem like much but you will quickly realize that you heal more and do more DPS.
Ignoring Game Mechanics
There are countless game mechanics in WOW that count. For instance, if you stay in the fire when you damage a boss, it becomes very difficult for the healer to help you. The entire raid can die and you would end up having to restart the entire fight. Educate yourself on important game mechanics so you know what has to be avoided before every single encounter.
