I agree, we've had quite the trend of novice rider's lately, and while I generally do like seeing stories from the start, it would be nice to shake things up a bit and drop us into a setting that's already in motion

I think Saber (a show I generally like) spent waaaaaay too much time slowly rolling out forms and character premiere's and it felt like that was at the cost of developing the plots and characters, so it would be nice to see them avoid that sort of problem for Geats

As for me, it all started with Gaim. In principle, I understand screenwriters: they want to work out the contract for toys as soon as possible, so that later they can breathe more freely and shoot what they want, and not what they were ordered to. But still, it would be time to come up with a way the best way to get around this.
To Saber's credit, since the Wonder Ride Books can change between the Riders, the initial forms weren't so useless and more like combat training for Touma. It's still better than the situation in Build or the current Revice.
I think the origin of an experienced Ryder can be shown in one of the additional specials. In W I remember the acquaintance of the characters very well inscribed in the crossover film.

If you mean "will they stab people to burn up their hearts and disintegrate them into piles of sand" I can promise you that's a hard no.

I was thinking humans turned into monsters after death.

Probably not. That's a lot darker of a concept than Toei is willing or able to go with anymore.

Well, we did have the Gifftarians in Revice, even if they were only around for a bit

Just wait for the movies:

Looks like Build left a strong impact on Reiwa.

Zero-One and Saber: Bike-phones and the ShotRiders.

Saber: Asymmetrical design and overall looked like a Build form.

Revice: Rex Genome did initially look a bit like RabbitTank. The Stamps look kind of like the Fullbottles.

I wouldn't mind if Geats looked like this, and the Beowolf theme would be cool.

I think Geats looks too similar to Build thus far

reagrdning female kamen riders everyone was salty Mei didn't become Espada, while I'm overhere salty Sophia never used Jao Dragon(or Kento barely using it for that matter) because it looks so freaking cool (I Get that it's suit was used to make Solomon and later Storious). On that note fastforward to Revice, I liked Sakura initially the problem is the show WARPS itself to make her relevant, loves giving her powerups because why the hell not, it feels like she's the ONLY character the rules don't apply too(oh what's that you want to give Hana a chance at life because she realizes the people who she surrounded herself with are psychopaths but she sold her soul to the devil (literally and figuratively) whelp here's a power up that let's you save her)

I've never watched Zero-One but the BIGGEST complaint about Zero-One I've heard is how horribly wasted Yaiba was
