Why are you just deciding this stuff through and through without any other input? Yuu pretty much suggested from the start that by chomping the jaws twice, each power-up would provide an attack function. Now all of a sudden that's changing for no other reason other than because you said so?

Yes. Tyrannosaurus would be strength throughout. There was no question there. I just think it would make sense if the fighting style changed a little given the fact that T-Rex are so... leggy. Likewise, the fiery arms of Carnotaurus promotes more of a punch focused fighting style.
Keeping in the spirit of modern Kamen Rider, I don't think "energy blades" is very likely, realistically. Yes, I get it. We're not selling toys here, but if it were a real show, you know they'd have to. I still think Spinosaurus should give him a simple sword weapon like the Daidaimaru. If he has a all-form encompassing sword weapon too, that mode has him dual wielding.
Velociraptor doesn't need physical claws, but I do think the attacks in that mode should be slashes. Like he zips past and around enemies sideswiping them over and over.
