Personally I think it is important to understand where your character's strength lies in and making the best use of it. This will of course be harder for you if you don't understand what approach you should be taking with your character; I will help you understand what your character looks like when played optimally at a high level. This will make it easier for you to build up a solid basis of a gameplan from where we can take your skill even further on a fundamental and on a character expertise level! I think there is a big difference between one's approach to the game and to a character; hence why I personally believe it's better to differentiate between the two and focus on said things individually. After all, the character you choose to main will be the character you will be learning a huge part of the game with.
