User blog comment:Fistful of Force/How early can you do dragon analysis/@comment-4834593-20120911155238/@comment-3486816-20120915104413

The enemy team should never be all top as early as the blog post is talking about unless they're trolling or something. Soloing dragon can work early game, but only if you know that your opponents don't have vision, and are reasonably sure they won't expect it (which is usually the case; soloing dragon early certainly goes against the meta, but they'll probably be suspicious if they see you pink ward it and clear their ward).
