Lets say wards are suddenly free! Yes, that means they cost 0 gold! Let the supports rejoice! But what consequences does this present us? How does it affect Hon and is it a good or bad thing?
Possible consequences:
Ranked games are no longer are plagued by lack of vision. If wards are free most players will use them.(especially low mmr matches)
Support heroes no longer need to worry about keeping gold stashed away for wards.
Gold no longer affects the vision of the team. Now proper vision is dependent on the experience of the player placing the wards.
