Wh... Why would you nerf the range of the sniper spec?
Deadeye's issue isn't really Kneel anyway. Being able to RP walk away from a hydra bearing down on me isn't gonna change much anyways. Deadeye is supposed to kill things before they can even reach you. With the range nerf, and the insistence that only certain skills can pierce, and that non-marked targets take significantly less damage from said piercing, and with no defensive boons to back the spec up like Bladesworn... Man. Deadeye wasn't good in PvE to begin with! Why make it do the one thing it can do, worse?
And for Vindicator:
I have a lot of thoughts regarding Vindicator. First is I fully agree with Anonynja.3172, the spec really needs better synergy between its skills and traits. Making the middle traits grant the Luxon/Kurzick skills some kind of interaction with one another would be interesting, and it would give a more clear middle-of-the-road type option for the spec. I know you want to avoid letting the spec do too much damage while also taking defensive traits, but maybe having it as a middle-ground with solid but not overbearing damage and defensives, while also having the option of focusing on one end of the spectrum fully instead would work. It would also make sense with the spec's whole concept, of Alliance Stance. As Anonynja said, Saint Viktor and Archemorus feel completely divorced from one another currently.
And second, please let heal Vindicator be viable. Even if you don't want to give it alac/quick, maybe letting it be a good source of stability for its group could work? Support Rev as a whole is in a weird spot, of neither of the Actual Healer Legends (Ventari and Viktor) are viable, simply because they can't bring the meta-defining boons.
