From beginning of this game i liked this community and people here,lots of them are my friends,those that i don't know i know that they are friends from somebody in this game,so yes i care when somebody leave and it is not the reason because i am a forum mod,i care because i am the person that cares about others,if you readed posts from my past that you can find it on my profile you would see that i always responded when somebody left!
Each of those persons that played this game leaved somekind of mark on our experience playing this game,those are our friends,our team mates..
