Hi again,

I must point to incredible work by Yarrrr. Both mods already have pretty good descriptions, thus I will copy the most relevant bits:

The Swarm is a quantity-based faction; They have a large team size and about 3 unique units can summon minions. Most of them boast high offensive power and speed allowing you to quickly overwhelm your enemies coupled with the fore mentioned team size. Their main drawback is that the faction lack supportive abilities and many of the units aren't very versatile due to being focused on melee offence, thus can easily be destroyed when it comes to survival or stalling. Good thing is that the core units come cheap, and you could use summoning to compensate the potential losses.

This mod adds 12 new heroes (2 in each faction) and expands the hero upgrade choices of the original heroes rather than the traditional ones (e.g. Orc can be upgraded to Black Orc instead of Chieftain only).

• The hero upgrades are based on the hidden or alternative upgrade choices that are possible in the game (So non-hero variants can get that upgrade).
  
• Several units are edited to have hero-only upgrade (e.g. Bowman, Skeleton Warrior)
  
• Excluding starting heroes, there will be 44 unique heroes you can choose to play as.
  
• You can still get the achievements of all the original heroes.
