Off-topic from the suspect discussion but,
One clear thing that has stuck out to after the greninja ban is the solidification speed tiers. When greninja was still in ou, so many players were using subpar scarf sets or relying on ridiculously fast new megas like Sceptile or Lopunny. This created unclear tiers for players during offensive team building. However, now that greninja is gone and pokemon like scarf keldeo, scarf latios, or mega sceptile are becoming increasingly rare, the golden speed tier -from my teambuilding perspective- is 110. Any offensive team I make has at least one, usually two mons that sit right above that speed tier. And no, this does not mean slapping a scarf on an already fast pokemon, but it means finding a well fitting mon who is more cohesive with the rest of the team.
Prior to the ban, almost any mon that sat inbetween the 110 and 123 speed tier was so much harder to use. Tornadus-T, a great pivot and pokemon that can provide tremendous pressure was shut down by Greninja simply because it wasn't fast enough. Houndoom was put into a similar situation in that Greninja could absolutely annihilate it.
Now, Pokemon in this speed range like Starmie or Raikou have even more important roles as they are revenge killers that can provide utility as well (a spinner in respect to the former, and a pivot in respect to the latter). Using hyper fast mons is now somewhat overkill when pokemon that can provide more synergy sit right above the golden speed tier. From what I have observed, gone are so many of the hyper fast revenge killers that existed in the days of Greninja, and arrived are the days of settled, more predictable speed tiers.
