I play in there almost every day, and ive never seen 2v1's or outnumbered sides become a problem. In 2v1 there is always a better player to be solo, and when numbers grow everyone is more than eager to switch about, sometimes too much so. One sec it will be 7v5, 20 secs later it will be 4v8.
I do wish there was some more higher alt fight starts however.
