10 XP = 10 gold. Three 1-costs, two 2-costs, and one 3-cost is also 10 gold. The gold value is the same but there’s a big difference: for the second case you have more flexibility in how to play the game.

That is, you can keep the units, sell to make interesting, or level.

Many augments in the same tier have similar functionality but you need to think about whether one has an advantage over the other.

Note Deisik’s comment on the choice between these two augments
