Wrong. Skill has a lower threshold of proof than powers/abilities do.
Powers are an unknown factor, they do not exist in real life, thus the rules that we know govern them can only be garnered from what we were shown. We can perhaps make reasonable inferences but showings > all.
Defensive teleporting, for example require that he has both the skill and speed in the use of said power to use it defensively. Not just the power existing. Just because you can teleport doesn’t make you Nightcrawler all of a sudden.
A person only needs to demonstrate that he is able to perform high level grappling/wrestling/martial arts to be able to perform the basics of said martial arts. A tae kwan do master who was only shown to do spin kicks will know the basic round house or front kick. We know this because we can see and know this IRL, the same way we can make inferences on RL objects. A car only shown driving at 90mph in a straight line in a movie is allowed to drive 10mph and make turns.
But you take it one step further than this. You go to utter stupidity/trolling by insinuating that a person who can grapple will only be allowed the techniques at the exact circumstances and order/sequence that he performed it in. People are not machines, they adjust and adapt according to their situation.
You want to apply adjustment and adaptibility for the arguments that fit you and deny such to everyone else. This is because you want to bait people into your trolling BS. This pattern of yours is well known.
And that is why you are a troll. And why we need a mod ruling.
Seriously, doesn’t it get tiring trolling people? The type of trolling you do scores ZERO intelligence points for you. It makes you look dumb, toxic and just plain annoying. Annoy-trolling is what 5 year olds do. At least Putinbot puts some cleverness to his trolling (well, most of the time). You just have people beat on you all day for weeks.
