The
difficulty of a battle, any battle, lies in your likelihood of winning.
In Elvenar, that is determined by choosing the right troops, and the ratio between the size of your army and the size of the enemy army.
Having chosen the right troops, the ONLY remaining factor is that ratio.
That ratio is set by the system, and
does not change when you change the maximum size of your Squads.
Therefore, a larger Squad size
does not change the
difficulty of the battle.
What is being discussed here is the
cost of the battle, which does increase as your Squads get larger.
Part of this at least is balance, because a person with larger Squad sizes should be able to afford the greater cost.
The remainder is where all of the so-called 'war games' fall down (and I include FoE in this). If you cannot afford the cost of a battle, then it is wiser not to engage in the battle.
