Just go straight into AK with your Blue quest set+some decent accessories(grand company has some I believe). After you get carried through AK once you can get your lvl 55 green Grand Company weapon. That's plenty to start doing AK without needing to be carried (assuming you are a somewhat experienced mmo player). Spam AK or the final two story dungeons to get philosophy tokens. Once you have mostly darklight you can start your relic quest and do the titans in order. It would be nice to get garuda wep before titan, but not really required.
