I hate doing forum posts but I feel like the LoS discussion for Dante's Tragedy means you really only have 2 options, Make LoS checks for all nuke abilities (Saryn Spores and 4, Volts 4, Mirage's 2 etc.) or you nerf the number and not the way it functions so it is still in line with other abilities. There's no way Dante was more disruptive to gameplay from a damage perspective than the other aforementioned frames and abilities and in that sense it also doesnt make sense to nerf nezha's augment which is a specific mod to do a specific gameplay that makes the gameplay similar to that of the other frames mentioned while sacrificing other aspects of his kit to do so.
I do think like many others have mentioned already the fact that his 3 already has LoS check should mean that Tragedy could exist without it. Again
I don't disagree with the overguard changes although I think there's different directions that could've been made but I also think people are overreacting on it a bit.
I will not test your new game mode until there's some form of better reflection and fix for the absolute gutting of Dante because the way I see it, if the new game mode is fun and enjoyable that will get nerfed too, atleast based on the current way things seem to be handled.
Edit: Scratch that, I not only wont play the new game mode this whole hotfix with all the nerfs to Dante, augments and CC kinda has killed my joy to continue playing overall. Goodbye until you fully fix things.
