Hi, I would like to suggest small technical change to consider.
Often when loading one would like to minimize game and have a look at your browser or whatever. The game pops back when loading starts instead of on character selection, resulting in being unaware of it and losing draft. In other games of this genre its solved differently and imho better (Not that I like other games better, I love all mobas and am loyal to Hots since cvery beggining). Best regards!
