*represses urge to argue at length*

Right, this is sort of what I was getting at. I'm cool with just a simple excuse for why they don't just go right to the final form too though. Like how Shining Form in Agito is solar-powered for some reason. It's weird, but it keeps Burning relevant.

Blade's King Form is so well done. Especially when you realize what he's doing when he begins using it like it's going out of style (That is, if you notice it before Tachibana explicitly points it out to the audience).

I guess to me it depends on the form. Only using Mugen makes sense to me, because it's the strongest. Sure, it might be overkill to take out mooks with it, but if you were fighting evil monsters, why would you want to go easier on the weaker ones? If the suit is completely OP, then it makes complete, 100% sense to me to continue using it over the base suit.

I do agree about the drawbacks though - it makes suits more interesting when the final forms have some. For example, Dead Heat. Sure, Drive gets more upgrades, but it ends up becoming Mach's final form, and he doesn't use it a lot because of the drawback. But he eventually manages to work around the drawback and use it to his advantage. From what I remember, it still takes a toll on his, but it's a lot easier to control. Using suits like this raise the stakes and are more interesting because of it.

So I definitely agree that final forms with drawbacks are more interesting, but they don't always end up like that. If they're using something like Mugen that has no drawbacks, it really doesn't make sense (to me) to not use it.

Given that his first name is Krim I would agree he is not fully Japanese. Also let's look at Professor Harley

So after watching Kamen Rider x Kamen Rider, Ghost & Drive, Im rethinking watching Ghost. At first I thought it was way too goofy and silly.

You were not wrong.

It's goofy and silly to be sure, but there's a lot of heart to it, and plenty of genuine drama. If you liked the stuff with him in Genesis I can assure you the show is even better.

*tearing hair out*

I'm going to give it another go when I finish the last bit of Genesis, count on it

I do like risk VS reward final forms, so I'll look at the final forms, including other comments in general
Ultimate: Become evil unless Gary Stu, become OP AF
Shining: Solar Power
Survive: No real reason, but given the series, make sense that you'd use this as much as possible
Blaster: Can't remember
King: Risk becoming an insane bloodlusting Undead for incredible power
Armed: You risk losing your oni powers
Hyper: Fuck you I'm Tendou Souji
Liner: Character Development solidified, and was needed so Ryutaro could fight with more than Mamotaros iirc
Emperor: Spammed only because the suit actor had difficulty with the other suits
Complete: don't remember
Extreme: Character development and slowly kills Philip
Putotyra: Stupidly strong, but risk going beserk
Cosmic: All Powers Combined but if your friends want to things without you it doesn't work
Infinity: Mana I guess?
Kiwami: Becoming an Overlord with godly power
Tridoron: Symbolizes the partnership between Shin and Krim
Mugen: HOOMINZ HAEF EENFINUT POTENSHUL

Decade Complete's limitation was having the worst possible suit ever.
