Battleground bug

I was in match, had question in clan chat, started answering it, got kicked out of bg (which i was winning) got - point, and penalty for leaving? seriously? what is even that?

Well, if your hero isn’t moving and/or attacking other players in the battleground, it’ll be marked as AFK and, if you persist like that long enough, you’re ejected from the battleground and given a debuff that prevents re-entering another one for a while.

So, the question is “How long did you spend chatting with clan instead of doing stuff in the battleground?” before you got kicked?
