The late debut of DoGaBaKi form were fine... If Garuru, Basshaa and Dogga had been used more often, it would be fine... And had Emperor Form waited for just 5 more episodes and DoGaBaKi had been used more during that period, it would have been fine... As long as DoGaBaKi Emperor had been used in the Tv Series a couple of times, it would have been fine.
Anyways... W's form change also seem a lot more swift than earlier Heisei Riders, having the base in each of Shotaro's memories;
Melee, Weapon and Ranged Weapon. Which gives W 3 basic fight modes.
Phillip adds to this 3 elements to supply the 3 basics.
CycloneJoker; Gives 'increased' physical power (Cyclone adds a sort of wind shell during punches and kicks with the right side, first seen against Cockroach Dopant in episode 7).
CycloneMetal; Adds the same 'wind shell' to each end of the Metal Shaft, seen against the Money Dopant in episode 3, and again in episode 5 while protecting bystanders.
CycloneTrigger; Here the Cyclone Memory turns the Trigger Magnums bullets to pressurized air.
HeatJoker; Provides the same kind of physical boost like Cyclone, making W have Fire Punches and Fire Kicks.
HeatMetal; Here the Heat Memory, makes it possible for the Metal Shaft having flaming ends, giving the Metal Shaft more power on hits.
HeatTrigger; The Heat Memory turns the Trigger Magnums bullets to flaming bullets.
LunaJoker; The Luna Memory makes the right side of W stretchable.
LunaMetal; Here the Luna Memory sort off turns the Metal Shaft into a whip.
LunaTrigger; The Luna Memory turns the Trigger Magnums bullets into Homing Shots.
Also, not to forget Fang, simply boosting all physical powers, also providing a 'boomerang', an arm blade, for regular combat.
Previous Riders did not have this much variety with, melee, weapon and ranged combat.
Cause of this, W can have a lot more swiftness with his form changes.
