Great system with enough variety to cover many situations.
Please consider taking trust "spells" out of the magic category in the UI, or at the very least hide them from the list in combat/situations where they can't be summoned. The main magic menu is so bloated with the myriad spells on most mage jobs that it is almost faster to actually type /ma "Spell Name+any punctuation +tier" <t> than to try scrolling down to those occasional use spells that don't warrant a macro. I'm sure there are people who do carefully select the magic sub-categories in combat who don't have this issue, but most people I know just hit enter on the main Magic menu. Give trust magic its own radio button on the mini-list. It would be a small, but very welcome change for those of us who tend to favor magic jobs.
