Destructive Forces
So what is the opinion on characters designed to counter magic/supernatural abilities? Anti-Mage expys and the like, I mean.
Like anything else.
It can be good, or totally stupid.
Anti-magic fields as a rule of thumb is something that I really dislike, even as a guy who is mostly into martial arts.
Because while it may be effective to just completely negate a characters abilities consider that you are removing a lot of that characters flavor and a large portion of that characters design.
By using anti-magic stuff, if its anything like the typical anti-magic field, then you prevent that character from displaying his skills and looking good.
You
want your opponent to look powerful and effective, because when your character contends with that opponent it will make you look just that more powerful.
Though you can take the other approach, and rather than negating the supernatural abilities you can form strategies against them...which is cool
because its forcing your opponent to use their powers in a less conventional manner.
