That’s not even an opinion – that’s exactly what really happened. The original game was just meant to be a once-off “beer & pretzels” game to see if it worked, and the rules were purposely written loose so players could easily modify it to however they liked. Even Wizkids was blown away by the game’s immediate success, and they had to rush extra printings early on because it sold out so quickly.
There were no tournament or organized play rules for it at all, and nothing was even planned, but there was so much player demand that they had to quickly pull something together, largely by modifying the tournament rules from their other games like Mage Knight, Mechwarrior, and HeroClix. The problem is that there’s always been a large disconnect between the precise, formal rules necessary for a competitive tournament setting and the game’s inherently flexible nature, and not enough effort was put into it (especially in those early days) to close up that gap, which is why all these years later we have a 50+ page FAQ to deal with everything.
