If we levelled our Trust by role rather than each individual, we'd be able to switch around a bit more, perhaps. Meaning we would need to level so many healers, dps and all rounders and could then choose from a list of available characters to fill the role. Personally, I wouldn't mind Trust levelling getting a rework.
I think the Squadron has been pretty much abandoned at this stage and can't see them going back to it.
The idea of the scions being my WoL's 'forever friends' wouldn't have bothered me quite as much in ShB as it does now. In ShB I felt part of a team, after EW I'm back to feeling like an errand-girl for the posh and privileged. Right now, I'm sick and tired of most of the scions and I'd like a break.
