Base and Translocator buffs look good enough, although I’m not sure why the CD on Translocator even matters too much. I definitely don’t have issues with it.
Stealth looks pretty good, but it takes only six seconds to recharge it. If you’re using Overcharge (not a great name btw, needs something a little better), it doesn’t matter too much and isn’t really impactful unless you need the really long invisiflank. Giving the stealth a longer charge/discharge cycle (ex. 16s max duration, 10s full recharge) might even eliminate the need for the slightly awkward overcharging mechanic.
Phase sounds buggier than release DF, and doesn’t really fit with Sombra’s character/kit.
