No point getting upset imo. Its part of competition... if my "friend" were way below me I might support them, but if they are competing with me for first, it is within the confines of friendly competition to support their opponent.

The friend list for me is strictly to schedule friendlies and receive a few gifts and maybe get some support here or there. Mostly I want gifts and friendlies though. I can generate about 100 rest packs, 200 morals and 60 injury packs in a season that way. plus the 28 gifts of each. Nearly enough skill points for 2/5 star.
