Viper directional change is fine only if they affect the Dreadwinder followups
Hunter's Coil and Swiftskin's Coil losing their positionals would allow breathing room for most players while maintaining the flow of melee3s. I can see the majority playerbase having a few issues double-weaving into opposite positionals.
It's only REALLY bad if they took out the melee3 positionals, which I feel is more the identity of the job than even Reawaken.
The main worry is what else they're changing, because they also mentioned changing more than just positional requirements... .
