I would be in favour of getting rid of "subjective" if we at the same time rename CW (a term almost no-one understands) as something like "poll" (lots of on-line communities have this concept) and then place an outright ban on subjective questions which are not polls, and get the diamond mods to get of their butts and enforce this. 

Having said this, more extreme measures may be needed to get rid of nonsense like this: http://stackoverflow.com/questions/2932407/what-superhero-would-your-language-of-choice-be unless you really do want your site to turn into a reddit clone.
