By the word 'meta', I refer to this question: what do people usually field and how do they usually intend to use it?

Apparently, the current trend seems to be monsters (e.g. Hydras) and hordes when it comes to low points games. To what extent is this true?

Specifically, assuming the above summary is true, would expect the 'meta' to change if the points limit is 800 and the character total limit is 200?
