I've been messing around with Skye over the last few hours, and picked up on something I've not seen anyone else mention: she has the most consistent flash in the game. It still suffers from some issues all flashes have, however, it has one major advantage.

With Skye, you know when you flash someone. If you send out a bird, and pop it, you will hear a small "pap" sound. However, if you pop it and it flashes someone, you hear a screech confirming that the enemy is full flashed.

To me, this makes Skye an extremely useful agent so that you can definitively know when or if a target was flashed. On defense, it is also useful purely for information. You can send a flash down C-long on Haven, as an example, and pop it. If you hear the screech, one or more is pushing, if not, you can rotate or reposition to garage/CT to anticipate a B or A push.

I could be wrong, but haven't seen anyone mention this. Seems like a great innovation for the new agent!
