You might also have to look at the skill a bit more into the skill and the cost for the skill as well. Since you could easily just take your opponent's rear-guard and retire it by calling over it.

So making restrictions on the 'Befriend' skill is recommended. Maybe such as not having a full field, or being unable to retire it. Though again this is your choice, I'm just looking at what could possibly go wrong with this.
