It's always fascinating to see how far characters have traveled across the tier list in people's minds especially if they've barely been touched by patches.
Mid Tier -> High Tier -> Mid Tier -> Low Tier -> Mid Tier -> Top Tier???
Top Tier -> Low Tier -> Mid Tier???
High Tier -> Top Tier -> High Tier -> Top Tier???
I think this says a lot about how tricky patches can be. You have whole characters that move up and down without anything really happening to them. Balance is tough!
I've also been thinking about something else recently:
"The US is the best environment to develop high tiers, while Japan is the best environment to develop low tiers."
In the US, the best players tend to gravitate towards what they perceive as the strongest characters, so we get to see them clash over and over, and get a really good idea of their interactions. In Japan, due to a variety of reasons the character diversity to average skill level ratio is much more even, and so we get to see how many more matchups play out at a high level, and everyone gets to learn from them. I think this is why Japan is where we see Duck Hunts doing so well, and why Kamemushi has been so consistent.
