Couple things. There are 2 rewards for completing Trust leveling. Glamour options for them and I believe a title.

Secondly, its a side content grind. Compared to squadrons .. Trust is much better for levelling.
Trust is intended to be slower, less efficient runs on account of it being zero queue time, solo for the same personal EXP as playing in a DF party. The DF party will always be the more efficient route, but Trust now exists to help alleviate queue times for certain roles.


Finally, Its going to take 4 jobs to 80 in order to max them out in an efficient manner.
Starting with Monk, running from 71 to 73 with rested exp, I achieved 73 shortly after they hit 72. Not wanting to 'waste' time running below my current top level dungeon, I opted to take a second job through the 71s, in this case MCH.
In doing this swap between MNK and MCH I can level 2 dps jobs of my own while also levelling 1 Healer, 1 Tank and 1 DPS Trust.

But what of the others you might be wondering? Easy. Tank job. Following the aforementioned path, Ill be taking Gunbreaker and Dark Knight to 80 in tandem. This allows me to take the second Healer and the last 2 DPS on their journey to 80.

End result is that I shall have 2 Tanks and 2 DPS jobs to 80 and all Trusts to 80. Winning all round. Levelling alt jobs was something I was going to do anyway, and this just means theres some extra rewards.
