Looking over at the Japanese Forum, it seems most people are positive over the removal of Noxious Gnash with some lamenting it going away.

And even the positive ones sadden by its removal, they don't seem to mind as it made the job less "stressful" for them.

I was shock to see it removal when I played it today and I was wondering at first I miss pressed a button until I realized they removed it. But, I don't mind too much... I did find it annoying to always re-apply, because it felt like I was just only applying Noxious Gnash most of the time instead of using my other skills. If they kept it, having it start at 30 seconds might've helped, but I'm not too sad that it's gone and they have increase potency and I do like having to do an never ending dance of attacks on my foe.

Really love how faster the class feels now.

So, I don't mind the Viper right now. It's more or less the same, just a little faster.
