Overwatch: 10 Things We Already Know About Sombra
3. Transporter Module (6 Second Cooldown, 15 Second Timer)
Enabling Sombra to manipulate natural forces and transport herself to a location of her choosing; this is a quirky twist on the conventional wisdom on what we assume a hacker to be.
Hopefully it will be a really useful tool for escaping combat or taking stealthy positions in PvP combat, too - especially when you may need a headstart getting across the map.
A quick cooldown time may be an aid to fast movement, but you can imagine a lot of frustrated players accidentally triggering their own demise, unless they practice extensively. Since Sombra will require a fair bit of practice to get right, a lot of lobbies immediately after release are going to be full of people trying to get to grips with these mechanics.
My advice? Continue playing as your favourite characters and learn how best to counter her abilities, before deciding how you're going to use them yourself.
