The word you're looking for is "subjective".All subjectable. I respect your opinion on Leixia, but it's a fact that Leixia's VERY VIABLE.
As for viable/unviable, those terms have been nothing more than meaningless buzzwords. No one is debating the possibility of a certain character being unable to win tournaments, it's a matter of how that character performs relative to the rest of the cast.
Disclaimer: This post is purely rhetorical. I don't care for either side of the issue, honestly. I will shamelessly counterpick if I feel the need to, and I think everyone should invest some time into learning a "good" character, if only for the perspective it provides.
