A lot of people have been saying this doesn't really change anything... but please consider what made Noxious Gnash (NG) unique!

As a result of the 11 second awakening burst and shorter NG debuff timers, It was imperative to re-up NG just before beginning your burst, ESPECIALLY if you had the resources to double awakening, and also to save a single dreadwinder combo near burst phases to safely re-apply GN for the following coils near the end of buff phase. Removing the debuff means you no longer have to (intentionally) prep or save resources before your burst phase, which was akin to saving gauge on BRD and being sure to only fire off at 90+ charge or holding wyrmwind thrust when buffs were coming back up on DRG. The serpent offerings guage manages itself easily and isn't really a guage you pay attention to, and your goal is to make sure you DON'T save too many coils for burst phase, as you were guaranteed to gain two charges every 2 minute burst, and at least 1 every other minute. Noxious Gnash was the only true fail point to pay attention too beyond pressing glowing buttons on a railroaded combo.

Having a button to press and knowing you need to save it is extra job complexity. Needing to press a button before a critical timing in rotation is extra job complexity, and the removal of noxious gnash single handedly removes it all.

Furthermore, the change from using dread fangs to apply NG to needing to swap between the two combos has had the side effect of removing the dancing between combos. If you open with 1-1-1, combo is now, repeating for eternity: 1-1-1, 2-2-2, 1-1-2, 2-2-1. Unless you mess up, you will not find yourself ever pressing 1-2-1, or 2-1-2. The free-flowingness of following the combo route has ripped out and replaced with Monk's Dragonkick-Bootshine, or DRG's combo cycles.

In addition to the NG issues, they also went overboard in increasing the length of the general GCD combo buffs, as with 40 seconds to hit the next finisher your 22 seconds double awakening combo, tied with refreshing NG with Dreadwinder and Spending your coils under buffs meant that you had to intentionally prep every 2 minute by re-applying your NG and prepping the finisher, so that you could use the finisher right on time! These are all not necessarily hard decisions, but the only true concious decisions to be made given how absolutely free-flowing Viper is made by design. Viper was made free-flowing specifically to load the weight of engagement upon the interactions of abilities to apply NG at the right time, and to prep finishers ahead of time.

Bring it back! This is far worse than losing Kaiten was and fundamentally changes the job from it's intended identity!
