This does actually bring up something - that there isn't necessarily 'the' OU metagame. Since the ladder pairs people with similar CREs, the metagame around 1200, for example, will be somewhat different to that around 1500. You can't ignore those differences, and to disregard the lower levels as irrelevant seems to me to be wrong. When it comes to recommending things to users, their skill level should be borne in mind - a team that does well in the hands of a 1600 player may not do so when used by a 1200 player, and vice versa.
You've hit the nail right on the head there Cantab. From 100-1499 its a much faster, offensive game, not disimmilar to LC. However, once you hit 1500+ it becomes much more stall focused as people try to preserve their CRE.
