No, many of the ideas are absurd, especially the hybrid ones. Some ideas were implemented (like self-moving troops), but if they were later removed, it means they weren't needed. The hero actively participates in battle while remaining outside the battlefield; they just need to increase the hero's damage output, and that's it. A defining feature of the series is that the hero dies only when their entire army is defeated. Therefore, they shouldn't be placed on the main battlefield. And I can confidently say that the developers will never read this, so none of the ideas will be implemented, which is probably for the best.
