I am a team leader. I would like to be able to do nice things for members on my team such as reward them for good deeds or gift them for special occasions.
Things that shouldn't alter the game too much that I think would be nice if I could maybe do:
purchase/extend boosters for them on their behalf
gift them items that I am not currently wearing that are in my inventory
gift them coins that I have earned or that I have donated to the team
maybe even just let us award some kind cute badges that could display on their hero page
I would even spend a nominal amount of cash if I could do something like buy a small number of donuts to give them like a quantity of 5. Maybe you could set up a new purchase category where people could purchase like 20 donuts that they could gift 5 at a time. Then they could give them out as incentives for joining or recruiting or whatever and you would still make money on selling donuts.
Just little things that might help them out and let them know that I appreciate them as members of my team. I got my first new team member today and I wanted to do something for her but I don't want to spend five bucks and purchase a voucher of 19 donuts for her. I think that is excessive because I don't know if she'll stick around or not.
Thanks for taking my suggestion!
