I think it's about time for Greninja mains to come to terms with the idea that their main isn't really that good a character after all. The significance of istudy's placing at Beast VI has always been overstated in a couple of different ways and apart from that we've only seen some occasional individual splashes from a handful of players - I don't think his results add up to more than solid-mid tier and by now we have enough observable data to take his results at face value.
These characters all have results that easily trump Greninja's - in terms of quantity, quality and consistency.
These characters frequently and consisently do well at various kinds of tournaments and levels of play. They also occasionally do well at bigger tournaments, moreso than Greninja for sure.
All of these characters have a couple of players that regularly perform well in various competent regions: [at least] Ryuga and Yoc for Corrin, Will and Hikaru for DK, Yusan and Brood for DH, Ryo and Waldo for Ike, Pugwest and Mr E for Marth, Umeki and SlayerZ for Peach, Holy and Longo for ROB, Reflex and Nasubi for Wario and Raptor, The Wall and Yika for Yoshi.
The best players of these characters also play approximately on a similar level of skill of the best Greninja player does, which basically means that Greninja competes with at least nine characters for his spot.
Then you have characters with individual results that arguably trump Greninja's best achievements:
* Motsunabe won a japanese major tournament with solo Lucario. He beat Nietono [Diddy/Sheik], Kirihara [Rosalina] and KEN [Sonic] in the process. Inconsistent character but more likely to win a tournament solo than Greninja is.
* Teiheita has beaten sever top level players in Japan with Lucas. Still somewhat of a wildcard character but it's not implausible to see him as a direct competitor to Greninja for their spot on the tier list.
* Shuton's 2nd place with Olimar at the last Umebura arguably matches all of Greninja's results. Wins against Nietono, Kamemushi and several other top level players.
* Earth won a japanese regional where he double-eliminated Ranai and he places regularly well with Pit.
* Trela winning a 260-man SoCal major with solo Ryu may or may not have been a singular occurence but Greninja is hardly in a position to dispute Ryu's claim for a higher spot on the tier list.
And then you have characters that have kind of fallen off the map, whose position on the tierlist is currently unclear but at one point had results that Greninja has yet to match: Villager, Pikachu and even Pac-Man had those.
If you add up all of that it's really, really hard to argue Greninja to be on the borderline between high- and high-mid tier. From Bayonetta to Toon Link there's already 16 characters that straight-up outperform Greninja globally and it's hard to argue Greninja to be better than Pikachu and Villager, not to mention Ryu. So we're already dealing with at least 18 characters we can reasonably be assume to be better than Greninja. But it doesn't just end there because you still have a crapton of characters who perform on approximately the same level as Greninja, about 12 I'd say. As things stand Greninja is floating somewhere between the 19th and the 30th spot on the tier list - that's about as mid-tier as mid-tier gets.
Greninja has a
lot of work left to do to show us that he's better than that.
