I guess that the less valueable 1 gold becomes (with current inflation), the more valuable AH playing becomes and the less attractive dailies become. However, tradeskill cooldowns are still very profitable. I have 7 toons with alchemy - which is a steady income of at least 1200-1400g per day for 5 mins of work and that without counting mastery procs.

Playing the AH can be a fun activity by itself though, even if it does require 2-3 daily scans :-)
