Version1: Instant deployment with enhanced durability, wider player interaction radius and permanent status (until destroyed or replaced)
Version2: TF2 style—build entrance and exit separately. Infinite duration and distance with, “charges,” that replenish over time to prevent continuous enemy flow.
Version3: modular place holders. Deploy a base structure that can have multiple functions. It can either be a Shield Generator or a Teleporter dependent on key presses (like Moira’s orbs) with teleporter only functionality when two charges are placed.
Theres not enough ammo in syms gun to justify having a ramp up, as soon as you can actually start doing work with a fully charged beam you have to reload, by which point the target has escaped or been healed.
It also wouldn’t hurt if she had power charge metre/counter like zarya.
I personally never thought of 3.0 tp as a bad, terrifying ability. It’s just that it feels as though Blizzard made everything else about her bad just because she has it. Which overall makes Symmetra kinda garbage.
