Well to repeat what I think,
Increase her survivabilty by return Photon Barrier by
Instead of her summoning Flying Turrets.
Have her Summon Flying Barriers again
and when the Barriers hit a wall or a surface have then turn into Turrets.
And for Teleporter (and Shadow step)
Instead of having the placement of the Teleporter (and Shadow Step happens within line of sight.
Have it happen with a 3rd person perspective.
(Aka think of the placement working similar to DF’s Ult But Like Junkrat you are vulnerable during it.)
(It’s also has limits of course, like it’s on a short time limit and a cooldown to use it.)
But the pay off for Reaper and Sym would be greatly beneficial for skilled players.
(said this before here but no point right now to bump the date 🧞♀ 344 Days Since The Start of this post about Sym (4/10/18)(3/20/19))
But in the end it’s up to devs what should be done…
I just hope they say something soon…
