Here is another option (alt 2) and the starting parameters for heroes:

This has a different concept:
1. Two Factions with a clearly expressed tendency towards a specific type of stats (50-30-15-5)
1) Orcs – leaning towards combat stats
2) Mages – leaning towards magical stats
2. Two Factions with a moderate inclination towards one or another type of stats (30-30-20-20)
1) Humans still lean towards combat stats (60 versus 40), but now there is no bias towards attack or defense, which I think is correct because humans are usually characterized by balance and the ability to choose their own path of development, achieving heights in any of them, unlike, for example, Dwarves (defense), Orcs (attack), Mages (knowledge), Warlock (spellcasting).
2) Elves, preaching the philosophy of balance and an inclination towards creation rather than destruction, now have an equal chance of receiving physical or magical stats (50 versus 50), but at the same time, they are more likely (60 versus 40) to receive passive (knowledge and defense) rather than active (attack and spellcasting) stats.
3. Four Factions remain with the previous distribution (45-30-15-10)
