Is Kasumi Goto overpowered because of Shadow Strike in ME2?

Based on the specific question in the title, no. Single target nature is what balances the damage. Area Overload and Incineration Blast are more useful overall against shields and armor. Warp can detonate lifted targets.

I also consider Flashbang to be her best power though, so if that was swapped into the question I would be tempted to answer yes. Multitarget CC against protected targets is unique, and it is the best power against Harbinger.

Miranda and Garrus both are slightly better than Kasumi in the pure defense stripping role, IMO. Miranda with party buff, and Garrus with high power damage. If you built Kasumi with Area Overload, you are pulling points from Flashbang, SS or Passive, Miranda and Garrus don't really have that problem (Miranda because she has an extra point, and Garrus doesn't really need maxed CS or any investment in bonus).  Of course the difference between Kasumi and Garrus on a synthetic heavy mission isn't going to be too large though, although Kasumi is easily better than him against Collectors.

I was (jokingly) expressing sadness at her dying. Because she's my favorite, apart from Miranda.

But now that you mention it, I have literally never had this problem. She always owns for me and I can't recall her dying very often, nor getting stuck. I do tend to disrupt groups of enemies clustered together with my own shenanigans though. I'm not sure if platform, class (she's dream team with my infiltrator and Miranda) or any other technical detail makes a difference, but I've never been disappointed.



Can't wait to replay ME2 and have her on my team again.

That's my experience too. In her Loyalty mission, when we face the YMIR for the first time, she always dies right in the beginning. I use your tactics. Put her in cover and make her span her Overload (She doesn't have Flashbangs yet).

I never got too much attention to SS specs as until now, and never realised that it was effective against all types of protection. That's why my question. 

Thanks for all your answers.

I never found the shadow strike thing that great.
