Co- ordination means nothing when the computer drops 3/4 of your party in round one because you weren't expecting it to have AoE spells that one shot your party members.

Sure you could reload and spread your party out more, but an encounter which assumes meta knowledge of enemy spells is terrible design. The same encounter at level 5 is fine, then you'll have the hp to avoid being wiped by level 3 AoEs and can recover.

On the other hand, at least Solasta actually uses the languages roles.
