A ranged class can keep Operatives out of melee range for 7 seconds (how long a stun lock really lasts for Operatives).
Certain ranged classes can keep Operatives out of range almost indefinately if they are skilled enough depending on their class.
Clearly, kiting should be removed because being unable to use anything except rifle shot from full to dead is dumb.
Again, being unable to get within range to use your abilities while you get killed by that ranged class should not happen.
Your arguments go both ways.
You don't have no one at all, you get another class. You always pick another class over an Operative because other classes are a bigger help to your team everywhere.
Did you swallow sadness, call a sex line, cry deeply, and demand a refund when you saw these patch notes, knowing that they will most likely go live unchanged since no patch on the PTS has never been changed before going live?
The point is you can interrupt casts, so unless you are a dps Sorc, your attacks can't be stopped by interrupts. This is why healing is significantly stronger than damage.
Being reliant on stealth guarantees a weak class in competitive play. Stealth should be a good way to start a fight in your favor, not a requirement to fight.
