Assuming the leak is correct:
I see where they’re coming from. Seems like they’re trying to make it easier to challenge players holding hard angles by relatively safely utilising a gadget that makes the job of the challenger much easier. Same concept as Ying, and basically a soft counter to Ela traps which have the opposite effect: making the job of the challenger much more difficult. It’s a soft counter since now both parties will be on more even terms.
However, in practice, stuff like this rarely works consistently. That’s why Ying (whose gadget on paper is great) is rarely used for that purpose. Now her gadget is almost exclusively used for pushing Defenders away/sound cover for when the planter goes in. Because if someone is holding off site, and you roll a candela in, there’s no way to know if they actually got stunned and how long it’ll last on them for.
Still interesting to see how it plays out.
And is there any info on the other 2?
