I am pretty sure FChamp is super salty that Full Schedule a near full screen Plasma Beam with the Viper ball tech. He has probably never been hit by that before and certainly no one has done that stuff before in a real match. I made a mention of it as soon as it happened.
Full Schedule was definitely doing stuff that most Vipers weren't doing before, like with his Seismo cancels and Viper ball stuff + mix ups.
If they allow Daigo and company to rewire their sticks for the Select Plink button then I see no problem with this to be honest.
In the grand scheme of things, this is less game influencing than using macros for plink dashing in MVC3. I guess the difference is that the game itself does not allow you to map up/forward in one button like they can with L+M+H.
That said I still have to give credit to a guy who plays Marvel 3 with 10 buttons.
I think the opportunity should be taken then to re-examine how these input devices are considered, because the way it is being enforced in this case - in my opinion - is just a receipt of how it has not been given enough thought.
Take the case of analog sticks on game pads being used. An analog stick certainly does not require input blending to create diagonal inputs (or any directional inputs) the way a microswitch device does, yet we allow players to use these freely.
Really what I think it comes down to is that the rule being applied this way is sort of a mandate that arcade stick gates use only 4 microswitches to create directional inputs, because the argument against the button seems to be that up-right is technically two inputs, even though on a stick it is one motion. This currently is not true for other allowed forms of directional input - there are certainly defined diagonal inputs on directional pads and analog sticks have an enormous amount of possible input values and just uses ranged to determine what individual inputs to send.
I would probably just move to eliminate directional inputs from individual buttons altogether, and require directional inputs to come from a dedicated part of the hardware which could be further defined within the rules (joystick, analog stick, directional pad). This way you can separate the question of whether it is acceptable to allow directional inputs as single binary button actions, separating the abstract question from the mechanical issues.
