I shouldn't bother trying, but some will be able to understand this.
If you look ahead to when SB/LA/HA have been researched, it's very clear in the data that Elf is the bottom of the totem pole. We're not there yet this round but we will get there.
Below is single-number production efficiency purely based on stat efficiency per 1000 gold. This converts all iron and wood costs to 100:1 to get every unit into gold cost. The market will go up and down which can sway these numbers some, but you can always buy at that rate.
| 🥇 Human: 42.96
| 🥈 Orc: 38.54
| 🥉 Dwarf: 21.21
| Gnome: 17.46
| Elf: 16.18
What this means across all Human units, you get 42.96 points worth of combat power (attack + defense + ranged) per 1000 gold spent.
This isn't the end all be all either, one of the beauties of Thardferr is that matchups make fights. Think of it as rock, paper, scissors with the strengths and weaknesses of Orc/Gnome/Dwarf/Elf, and then the nuke is Human. Orc is good vs Dwarf. Dwarf is good vs Gnome and Elf. Gnome and Elf are good vs Orc. Gnome vs Elf is a blood bath.
