Where to start with fresh lvl 50

So i just dinged 50 on SCH and was wondering what to do 1st

First of all, pick up your level 50 coat & spel then head off and complete all Hunting logs for your GC and get to the highest rank.
Or you can start your relic quest (in order to start it you need to have completed all mai nstory missions). Or you can start farming Amdapor Keep. :).

Finish your Class & Story quests. Level your GC rank and get the ilvl 55 weapon. Proceed to mindlessly farm Amdapor keep and Castrum for a few weeks.
