The idea of adding a weakness is bogus. xDIf there's a facet of the technique which has a drawback it's a descriptor, so it goes in the description. The weakness just serves to invite people to metagame (something I've historically had a lot of trouble with).

Not every technique has to have a weakness but for the ones that dwell in the realm of near impossibility it is kinda needed... 
Well just because it is listed in the description doesn't mean all character know it's flaw in game but I understand how the temptation would be there for some.
