Of course I'd never take him because I consider his ability broken, but if theoretically I did I'd accept he's a dead man and just take him bereft of upgrades.
I've had to kill Biggs plenty of times when I first started playing and it's never really been more than a slight annoyance.
I would be interested to know about your definition of broken if you consider that he's never been more than a slight annoyance.
Broken as in it removes choice from the other player as they must shoot Biggs, and I consider removing choice to be bad design.
Now ion effects take movement away but to do that they must first hit you, you can counter ion weapons with manoeuvring and by rolling evades, Biggs is always on and it's far harder to get around his ability.
So I guess that Captain Kagi is also broken since you must TL him, Jax is broken since it removes the choice of taking an evade or focus action while at range 1.
Maybe broken was a little too much of a word. Considering it a bad design choice, now this I can understand.
