Simply cuz they were expensive.. whoever bought it for perm won big time. When Nexon gave it out free for one month, everyone was in a fit. The problem with mutagens was that it made Quar even more blatanly pay to win than it already is (recon  vs light vest blah blah blah). I think people didnt' reject it cuz it was and still sort of is rare today.
