Depends on what you define as "sucked". As a form of entertainment and sustainable business model sure, but that was not the original intent. The intention was to put people from different martial backgrounds up against each other to contrast the "street" effectiveness of their styles, not to create a style (and a sport) in it's own right. The goals have shifted over time out of necessity in order to meet licensing laws, health and safety regulations and frankly to sell tickets, but a real case could be made that the earlier form was more interesting from a purist's point of view in that it was far more reflective of the practicalities of training in a given style or styles. I played around back in the 90s relying on a makeshift combination of boxing, judo and kung fu (of which the first two I'd competed at amateur level), but that would in no way stack up in the modern game because the main skill set I'd bring to the game above and beyond current competitors would fall foul of "dump'n'hump" rules. I can't wrestle to save my life, but I can strike and grapple if needed. Those rules were brought in because the most effective skill set in early competitions was also the least entertaining for a crowd, in other words creating a spectacle became the focus and supplanted contrasting disciplines. None of which has any bearing on the thread mind you.
