Hey Sportscaster! (5)

Hey Darren Pang!  Stop using 'reactionary' as a synonym for 'reflex' or 'instinct' or 'reaction', because it isn't one.  To paraphrase Inigo Montoya, "I am certain that it doesn't mean what you think it means."

(from thefreedictionary.com):

re·ac·tion·ar·y  (r-ksh-nr)

adj.

Characterized by reaction, especially opposition to progress or liberalism; extremely conservative.

n. pl. re·ac·tion·ar·ies

An opponent of progress or liberalism; an extreme conservative.

So stop it.  If you want to say a reflex save, or instinctive play, say that.  It's perfectly fine to say that a move was a reaction.  Don't add syllables to a word to turn it into an adjective, it doesn't make you sound smart.  It does the opposite.
