My thoughts exactly. This is the 2.0 bundle reintroduced.
Though I don’t mind (besides the smurf aspect) as I’ve actually advocated for this for years 
It will get new players into the game much faster, instead of them grinding heroes for weeks/months.
One reason why people don’t switch to other MOBA’s is the time investment required. This will drastically cut down on the time investment needed to unlock much of HotS.
