Hello!
I'd like to offer some suggestions / ideas on how to make these more worthwhile. Some of us spent a long time raising our Adventuring Fellows up to max level, completing several quests and stories to do so, only to have them completely obviated by Trusts. These characters have a more personal value, and are, in many ways, sort of like our very own "custom" Trust.
The first thing they absolutely need is the standard Trust ability to quickly recover HP/MP when not in combat. I'd also like to propose that their battle capabilities / battle parameters (damage, healing, accuracy, etc.) be boosted beyond the scope of a standard Trust's, as they are not considered part of your party, and therefore other Trusts do not interact with them. It would give us more incentive to use them.
One way this could be done is with new training manuals, perhaps unlocked through login campaigns. Maybe some of the AI routines now available for Trusts could be given to your Adventuring Fellow through these manuals.
I'd love to be able to use my Adventuring Fellow again, but as of right now, there's no reason to use them. They are entirely outclassed by Trusts in every respect. With boosted capabilities and new AI routines, there would be cases when it would be beneficial to have them present! I'd love to see them dealing respectable damage, or healing on par with a Unity WHM Trust. Just something to consider.
Thanks!
