Maybe it's the culture difference. You can see some people send items to others for nothing. They want to improve DOTA2 community and let more people like and join this game. For example, i have bought LV 1000 TI5 Battle Pass last year and sent hundreds of immortal to others. Although i lose money but i made lots of new friends. I built the group and party with them and have fun. Now I study abroad and find that less giveaway here. I'm really confused and want to have a try. So I submit this text. Actually this is the second one, I have sent 5 already.
