For me, the community. Some people seem to avoid them but I get at least two messages a day after beating people calling me a scrub or a noob or a spammer and most recently "wannabe pro". I wish there was the option to block any messages getting sent to you. I do ignore most but when I see a notification I just think *sigh* As for in game, nothing really annoys me too much at the moment. I dislike lanterns might but that's about it. How about you?
