I really want to orient this topic about if she will be viable or not instead of asking "Who will be strong on Neon", we aren't even sure she will be picked enough.
So. I'm not 100% sure of the fact Neon will stay bad, but I don't think her change are relevant, I want my duelist to take spaces 1st, not to takes duels, sure she will have more kills thanks to slide, but nerfing her wall and not making her stun better (While the last spell of Raze and jett are literally a Z-axis), will not help her to take spaces, wish mean Jett and Raze will still probably be favored. Sure her ult will be stronger, but do you really think that will be enough to make her viable ? Do you really think her ult is better than Chamber or Jett that can keep their ult all the round ?
Also that raise the question : How do you play Neon in defense ? Thanks to verticalityand mobility, Jett and Raze can take a lot of line that can surprise, and I think Neon can't really do that. Maybe Neon's hope is on operator, I think Neon is a good ope, her moovespeed allow her (in exchange of a small stall) to be sure she can always be in position to take the line before attack push, but i'm not sure if she is used like that, some people gonna argue that she don't have the "free out of jail card" that Chamber and jett have, but retaking with ope is so hard, that be sure you will be always on the site that get push might be strong. (But maybe i'm delu about this.
To conclude, I think she is still weak, but I need more ideas, more point of view to have a better opinion on, this that why i'm really curious, and I would love to hear long paragraph about what you think.
What is your point of view guys ? Do you think she will have play rate ? And if yes, how mush ? Which map do you think she will be played and why ? (Please try to give argument please !)
