EXPERIENCE:

1°) Hero Experience:

To be precise, the hero receives 1 point per killed unit and 3 points per destroyed structure (even temporary structures) by his troops or himself. We could mention the XP received for completing quests (along with the Knight upgrades), as well. (For titans and enemy heroes, I'm not sure)

2°) Unit Experience:

Each unit receives 1 point per unit it kills, 1 point per level of Hero it kills (for a killed Titan, I don't know), and 3 points per structure it destroys.

Is it the right place to tell on how an unit is upgraded when reaching a new level?

Some upgrades are trivial (more HP, more stats), some are interesting (spell level for spell casters); some are fixed (+1 combat), some variables (change of HP gain per level),  some are interesting ((rather) weak units allowed to become strong at high level (e.g. Giant Eagle and Dryad)).

Also, we could speak about the increased initial army points it takes to bring high level retinue troops into the battle (e.g. at which level it costs one point more).
