I watched over 30 attempts last night alone, and every group was geared columni or better and all failed.
To be blunt
It's over tuned and not worth the reward.
So gear makes u a good player? The reason people are failing is probably due to the fact this is the first instance they come accross which actually requires some competence behind the pixels of the characters and unfortunately the majority of those columi players would not have seen any mechanics like the ones in this flashpoint. Not only do you have to have competence but the rest of the team does also.
I have done this in a full tionese/columi team and it wasnt that hard but then again we have all done this fp alot with our mains. The current difficulty is fine but it takes tactics and competency and I believe thats why they failed.
