Sonic Fox's tier lists receive most of the community's attention, but I am finding that Ninja Killer provides more comprehensive explanations that exclude "This character is OD / broke / stupid" every second or third sentence. I am about halfway through the video and I am learning a lot. Ninja Killer is also the best flawless blocker in the community so listening to what he has to say about reactable and unreactable offensive strategies is interesting.
I also still believe that Highborn Kitana is top ten. I feel people are overrating Shang Tsung, though. From what we have observed in recent online tournaments, he is mostly used as a counter-pick character. The top tier characters, namely Cage, Cetrion, Geras, Jacqui, and Liu Kang, can punish a flawless blocked ground eruption very consistently, but I have only seen Ninja Killer flawless block and punish it regularly.
