@Albus/Aaron: Stop making reasonable suggestion about BG. I cannot comprehend it.
As for Ninja/GS overall, yes they are not meant to be trans class type of power, but they should at least find their way to be at least usable just not as good at it. However, they are more like a total uphill climb to even survive in pvm. As you said, making them how TKM/SL turned out to be should be the real goal. Plus, who restricts us to follow official server? Just cause they made it so ninja/GS are the most gimmicky ever, pserver certainly got the power to change it. We're totally doomed if we have to follow iRO in their planning...
