Have you thought of adding BCNMs to the mix something that is not Primals but has a very good challenge and a possible Rare/Ex drop. There is currently nothing in the game where you say man he got that Ultra Rare drop like a Kraken Club, Ridill, something of this nature. Extreme Primals is fine but seems like replayed content and will be fun maybe a few times and people will lose interest.

I know fates are fun and all but 16 man dungeons(premade groups) would give the FC something to do, seeing as CT is 8 man >> 16 PUG group...
