Once you hit level 56 and unlock New Haven you get an unlimited gear farm. If the main reason to have the friends list to be capped at 100 with only 50 energy is to prevent gear/bar farming. Now at this point of the game I would like to help support my guild mates boost there shops more than anything. At 50 I can only do 10 members.
I suggest boosting the friends list max to 200 (so you can add people outside your guild) & to boost the energy amount to 100 if not more once you unlock the gear farm.
Bars are pretty much irrelevant except for navy or repairs/healing anyways so buffing the friends list at this point in the game would just overall encourage community members to help/support each other a lot more
