When Overwatch Team added The summoner (Dragon symmetra-Skin) they also added new voicelines for everything, Abilities, Ults, On fire.
Does Summoner gonna have voice line for Phoron Barrier?
Event version, if we’re basing off Witch Mercy, will likely still have her Shield Generator, so not likely getting a new voice line
Difference being though is that Mercy has always had rez in the game. The shield gen has been completely removed so not really sure if the Summoner version will keep it as well…
And remember when Mercy first got the Valkyrie ult, the witch skin didn’t actually say the voiceline for rez, it was patched at a later date.
