For me, I'd love to see the early waves of the post-license work put heavily into art upgrading, especially around the hero models and older costume textures. The visual divide between costume pieces in 2005 and 2012 was almost painfully massive, so doing more to at least bring the 2005-era content in-line with 2012 for a more consistent look would be great.
While it may be a bit much to ask for, more detailed face manipulation would be an amazing upward step in hero crafting.
Cost-wise, I would be willing to actively pay to support the game but would appreciate that payment being optional and free of randomized-result mechanics like the cards that were added in, IIRC, i22. I'd prefer to see the game's formal reintroduction to the world not get an annoyed Jimquisition about it.
