i didn't say all, i say most
like AP system+card select for blade riders, put on/cast off for blue gauge Kabuto riders , the rev system for Accel, buckle grab>various drumming katas for hibiki, the whole Fang Joker BW moveset, etc.
My bad then.
What I can see is they can make Blade like Fourze, his Rouse Card can be toggled for his Special Attacks (no more slow SP Tackle >.<). There are cards that involve his sword, body and punch/kick so three analog stick to chnage it. This mode will be green gauge. Finisher could be Lightning Sonic/Blast.
For Kabuto, the Put On can be included on Kabuto blue gauge. Just set the it Down Special, which give him superarmor or recover his Guard Bar back, which can become a whole new style of play for Kabuto. Some of his movesets change to adapt with the bulkier form and have ranged attacks. This use 2@3@4 rider energy. It stay as Blue Gauge.
Accel should be added other two mode, Engine Blade ability toggle and Booster form.
-Engine Blade toggle can be toggled using the analog stick (usually for forms).One is for Engine Blade power (Steam,Electric,Jet) which will change Forward SP, while another is for his AccelDriver (either Accel or Engine Memory) which change default SP. Finisher can be Bike Engine Dasher (ram opponent while in Bike mode) or the finished form of Accel Glanzer (default SP)
-Booster form is just like Trial (red gauge). That's all I can say for now >.<, didn't know much yet about his moveset from BW. Since Booster has little meoveset, his finisher will revert him back to Accel form and execute the AccelTurbuler Phoenix (the one used against Terror's dragon monster >

)
For Hibiki, the different katas may be possible with his SP being the buckle grab, and once succeed to grab opponent, the player will be given to use different katas from default SP, forward SP, and Down SP. This can done right with Hibiki Kurenai which in Climax Heroes atm has limited combos (but strong and fast >.>)
Haha if they done that for W FJ, it would be overpowered
Anyway, all of your suggestions are nice which can make Climax Heroes a better game :thumbs:
