At this point, the only Caster I want is one where you can choose the Elemental aspect of your kit, so that way, you can be a full Blizzard mage, thunder Mage, or hell a water mage. I'd give them a Crystal orb or something of the sort for their weapon, something non-intrusive but still adding a conduit for the casting effects.

As for Scouting, I got an Idea for Thief: A single-handed Dagger that uses steal to build charges on 'tools' by 'stealing' them from enemies. The Tools themselves make the most of the Thief OGCDs. Such as a rope knife for engagement and a smoke bomb for disengaging. still workshopping this Idea as well as the caster one, but I like these concepts, barebones though they may be.
