this was a poor choice of topic title for this question, but it sounds like you'd enjoy Dominator or a VEAT. With several exceptions, Defender and Corr action economy is often used on a debuff cycle at the beginning of combat that means you still sort of "stand back and do X," and then combat's over. VEATs, particularly Night Widows and certain Crabs, have a more involved cycle that requires mixed ranges and awareness of team position. Dominators need to use melee, range, and controls to get the most out of their class, and so have a multi-stage engagement process that can be very satisfying when it comes together.
Can you tell me more about the VEATs like their strength and weaknesses or what resources they bring to a team? Or even better point me to such a resource?
