Viper Changes are good, actually

[Reinha]

Is the boss going away and will it be a damage loss to refresh NG?
Should I delay using a Dreadwinder to avoid overcapping NG?
Should I use Dread Fangs before Dreadwinder becomes available?
Will my NG last long enough for Reawaken? What about a second Reawaken?
Do I have time to dump coil stacks before NG falls off?
Am I letting the NG timer fall too low to allow for sudden disengages?

Is the button glowing?

Now you don't need to think about when the boss goes away or when you have to move away from the boss, when you use Dreadwinder, when you Reawaken or when you use coils. Just press the glowing button. The game shows you the answer with a dotted line instead of you finding the answers yourself by experimenting and learning. All of the things you had to consider and plan for were removed and the job is now objectively simpler and more one-dimensional. And for what? Viper was the most played job in the game, it didn't need to be simplified.
