yes, and there in lies the one the core issues. you can go right into ranked games on a new hero you have never even touched before and play like crap. you dont know what you should pick for talents, how to play them effeciently, or anything else.
i would just like to insert this here since the problem has been around since TL obviously. however, they had a legit chance to change things on the merger of HL and SL to make things better for everyone.
