How much do you predict we will see of this?

I don't think we would see it too often

I use to use marksmen on Kath but found for points being spent a lot of times her ability didn't proc

Your counting on your opponent to cancel crits,and investing in that is kind of counter productive. Relying on my opponent to dodge

I do like Mara on the fire spray, but now it really becomes a huge target.

I think it'll be fun

I would probably try it out for a game, but I've had games where not once had my opponent canceled any crits from her. Even with marksmen

I played a game where I put push the limit on her and it worked very well. Really kept her alive a lot longer getting an evade and focus, though she doesn't have much green maneuvers.

Could put expert handling on her with Mara to help get into that range one position.

Stress is nice, but it gets really overvalued when people start basing lists on it rather than causing damage. All of these stress abilities were, IMO, put into the game to make stress relevant when most people discarded it way too easily. I think the goal was simply to make things like PTL, Opportunist, maybe even using red maneuvers to excess, less automatic and potentially more challenging. It should be a tool used selectively, not something that will pay huge dividends if you go "all in" on it.

I think Kath isn't the best target for Mara. I'd say throw he on the generic or maybe on Krassis to keep people at range 2+(although I think this won't work well.)

Kath + Ion Cannon + Marksmanship + Tactician has the potential to be quite amusing.

I always found it hard to user the ion canon.

Just for the fact that is rather do 2-3 points of dmg over possibly one
