6) Practice in a “Safe Space”
Building off of my last point, practice in a safe space. This can be a guild group or a group of your friends. These people will not yell and scream at you if you miss a flag capture or forget how to heal or if you accidentally pull an extra group of enemies in a dungeon, etc, etc. This is absolutely a must for the tank/heal roles as you will mess up and you will make whatever group you are in pay the price for it. In a random group you may get kicked out which can be disheartening and more importantly, can rob you of your chance to learn from your mistakes. If you don’t have friends who play, go find a guild 🙂
