Well, it's kind of nice that Riot released a fully specialized champion (in this case, positioning), but at the same time I feel that it's sad that the overspecialization kind of becomes a crippling flaw at the same time. Niche picks always make me kind sad.
That said, I wouldn't be surprised if Riot will continue and try the trend. They did state that they were going to release newer champion with less frequency, but that they would try to polish them and make them more unique in the process, I guess.
