[Houserule] Changing Defaults to Techniques

[kirbwarrior]

As PK wrote here under #14, he has it so Combat Art and Combat Sport can be bought off as techniques. I've always been bothered with how buying defaults off works (namely, there is no reason ever to do so), so I was thinking of applying it to all defaults. Does this seem too good? Is there any weird side issues that come up?

Thanks ahead of time.
