I don't think it was a bad idea for this supporting feature in the first place. Now it became very frustrated when there are always a same group of supporters (which are friends among them) go in to my game and support my opponent. Although my opponents are not a friend to this group, they still can go to the live games such as cup or within same league/champion etc.
The reason why they are always supporting my other side probably because I beat one player of this group in a league and he lost the top4 place to enter the Champion next season.
Now they had been haunting me like this for more than 4 seasons, no matter how early or how late my live games are, they are there to cheer my opponents.
I don't want to give names but they are Thai. The supporting feature is now a revenge tool for them.
What do you think?
