@jaygates879 I see her tac somewhat like either a backup or a second wind, as I almost exclusively fight against her it often goes: shoot people - they get shields back - I die xD
It's hard comming up with new abilities that are entirely different, usually it's a slightly different take on an existing one + the combination of skills that make the new character work or not.
I've been doing concepts like that for a while and tend to look at what systems are in the game already to see if you can do something with that.
I.e: What about crafting mats? What about skill cooldown/energy? Transmutation of gear (Loba alternative).
And for movement, what about a platform that just goes up and down but can be stationary. Things like that.
