The AH does need a desperate overhaul. A search function should be #1 priority on SE's list for adjustments to the AH, if they were to have any.

But an enhanced search system would greatly benefit the game more than an enhanced AH, especially now with so many different things players may be interested in (Missions, abyssea, magian trials, etc). The less-used categories like synthesis and other would just be icing on the cake when it comes to being able to comment them alongside everything else. Not to mention the ability to put your flag up for grouping and the jobs you have available at different levels for anyone at ANY level who would /search and have you pop up.

Enhanced search feature would speed up the game, make getting into groups faster and finding people easier, more than an enhanced auction house could ever hope to accomplish. Not to condescend your opinion or anything; I agree with you. But /seacom is #1 to me, AH #2.
