Viper's current gameplay embodies the jobs fantasy perfectly. It's fast, it's flashy, and deals tons of damage. If you are gonna touch anything please do not touch the speed at which Viper plays. It's probably the most fun melee job you've created.

Also removing positionals means removing the last bit of player skill expression this class offers. Because apart from positionals the only difference between a good viper and a bad one is just Reawaken usage and thats not good enough.
