What do you think of this system of battle. Personally I find it is the main reason why Shingeki fights are so appealing.
It's just unrealistic enough to make them really fluid and give this touch of supernatural that is always appealing but in the same time, they keep some technological weakness (limit amount of gas...) that give some challenge.
Its an awesome idea...i'd buy one if i could and i never considered buying any such otaku thing. I'd defer with the OP on the point of its being unrealistic giving it a supernatural feel. I'd say it totally gives a gadget feel. Like bond gadgets, or bat-equips...which are all more or less unrealistic, but hardly supernatural.
