Benefits to friendlies:
-A small amount of gate receipts.
-Another opportunity to help increase the chance a player will maintain or increase form.
-A chance to experiment with orders.
-Small experience gains.
Downsides to Friendlies:
-Small PFL drain (1/3rd that of a OD Match)
Friendlies do not affect Team Morale, Sponsors or Members Confidence. With no effect on members confidence there will be no effect on the number of members gained/lost during the week. Only competitive matches effect the members confidence of your club.
You can make a friendly challenge by going to another team's Pavilion page, and using the Challenge Team feature.
