I personally don’t want to see Symmetra lose her damage Turrets, just give her an additional 3 Turrets with a specialized healing function which can be toggled with the mouse wheel.
She’s a builder more than a support. If she was to become support again it will be towards shielding, but that’s not really needed of her kit anymore due to other support heroes that can fulfill that role easily. Her beam and turrets needs some buff. More turrets and beam going through enemies at max level and barriers. Increasing her ammo count to 100 is fine.
However if they want to make it an easy buff just add 3 more turrets to the kit reducing the cool down by 4.5 seconds each because 6 turrets is a whole minute and they get destroyed a lot. The beam can apply a snare and at max extremely slows down the enemy. Right click ability can be buff to do more impact at max damage causing a slight knock back or .5 second stun.
That’s the only thing I can suggest for Sym.
.5sec stun.
(sarcasm) yes, let’s replace Sym with another DPS kit, then a year later, let’s replace Sym with another DPS kit, then a year later, let’s replace Sym with another DPS kit, then a year later, let’s replace Sym with another DPS kit, then a year later, let’s replace Sym with another DPS kit, then a year later, let’s replace Sym with another DPS kit, then a year later, let’s replace Sym with another DPS kit, then a year later, let’s replace Sym with another DPS kit, then a year later, let’s replace Sym with another DPS kit, then a year later, let’s replace Sym with another DPS kit, then a year later, let’s replace Sym with another Tank kit, then a year later, let’s replace Sym with another DPS kit, then a year later, watch the world burn, and then let’s replace Sym with another DPS kit.
Sym 1.0 did not heal, she was put into the support category because she gave her team shields, which is not healing, so going back to her support roots does not involve healing in any form.
