Is a first order team too squishy?

Itscaptainphasma, in my opinion officer has great support skills, and can grant 80% turn meter to another character, or take 50% from enemy
He's good to prevent a bariss heal, or a maul attack, but he hits kinda low so far. His health and defense seem average
Overall, only use him if you have a heavy hitter that he can grant turn meter to

Have Phasma as leader, and put Old daka into the team, squishiness becomes a non-issue unless you're up against a very fast AOE team

Anything but a very fast AOE team, Old Daka can literally mitigate a significant amount of damage due to her basic stun... GIven Phasma's ability to give an increase to your turn meter, and also slow down the opponent's team. The FO is a very fast high impact team...

The real linchpin in taking out the FO tie pilot as quick as possible... but because Old Daka is there, that may not help you as you need to take her out first before you take on the TIE pilot. Else there is a very strong chance she will revive him further along... If the enemy team is truly evil, he or she will throw in the Ewok Elder just to "make things interesting".
