Should all heroes be free?

[Kith-11735]

I argued for this, once upon a time:

@Kith-11735

• Make Unowned Characters available to play in all modes, but unable to gain Experience from matches (and therefore cannot generate levels or Chests) or access Collection items (and therefore cannot be customized, forcing them to use the default Skin, Mount, Announcer, Spray, ect). Matches completed with Unowned Characters would still count for Quests and earn Gold from completed matches.
• Change the Free Rotation from Temporary Availability to Temporary Ownership, allowing players to build progression on characters that they have not obtained and play around with their Collection items for a limited time.

I still hold on hope that Blizzard will one day make this change (or one similar to it). It would be so good for HOTS.
