DEC 10 Trait changes: Thief
I think you’re making too much of an issue out of it.
Yes, it makes D/P permastealth impossible. That’s a good thing, because permastealth effectively allows the thief to reset a battle as many times as they want.
In case you don’t realize it, the actual initiative regen is getting boosted. Currently, you have 0.75/s base, with a potential additional 3 every 10 seconds from Infiltrator’s Signet and Quick Recovery. That averages to 1.05 initiative/s.
With the change, you’re looking at 1.00/s base, with a potential additional 2 every 10 seconds from Infiltrator’s Signet and Quick Recovery. That averages to 1.2 initiative/s.
Also, Infusion of Shadow is not affected if you don’t chain your stealths. So if you’re actually using Backstab, which you should, it’s not going to change anything.
