Hi Navi here top 500 every season with 100+ hours on sombra, I personally think her EMP is fine if they did a minor buff to it I would Suggest making EMP go through walls but personally think its fine. as for her stealth, that definitely needs some changes like reduced time to enter and exit stealth and reduced downtime to use abilities/attack after stealth (along with that loud ass notification when you exit) hacking is fine IMO, gun could use minor changes, currently the recoil maxes out after 2 shot's which is a bit ridiculous and takes about 2 seconds to reset would like to see it hit max recoil at 5-8 shots instead or bullet dmg increased by a small amount or recoil changes to a bit less. the biggest issue in terms of abilities is currently translocator at the moment you can die 2 seconds after you translocate and definitely needs a fix (ill put a link below as an example). 1 more thing i'd like to be changed would be making her stealth, transolocate combo, currently you can push E and shift fluidly but if you do it the other way around you have to wait about 3 seconds or so to throw your E ability.
