Great Guide for newer players. I'd like to add something about Relic Sets, Relics in this game can be very RNG and sometimes your luck is horrible. But my advice for newer players is to not focus as much on specific sets but rather the stats/substats. Until you are later in the game and can farm for best in slot 4pc sets, its often better to go 2pc/2pc or even full rainbow (no set bonus) if the stats are what you need. Relic farming in this game can be a chore and it may take forever to get the perfect set. I tend to farm generic sets that are more universal. The two big domains that I farm are the ones with the Quantom/Guard sets for DPS and supports and the Longevious/Hackerspace for Supports. These 4 sets are good enough for the early to mid game and then you can start branching out.

It's good to know the devs actually play the game and can actually make official guides. Imagine if SQEX did this for DFFOO instead of the community having to relay entirely on third party tools...
