Certainly, maxing your uptime on it in movement situation will help further dps even more (Thus the Mindflay glyph), but the big reason why its channeled is so you can interupt it WHENEVER you feel like and not feel like you just lost some dps, akin to any dps that have to do a full cast time spell, such as mages... and... Balance Druids!
So, no. Mistweavers get the channel non-interuption because they are HEALERS, and because thats thier go-to heal for most situations. Spriests SHOULDN'T because this is our filler spell, and the fact that its channeled is SO that our dps isn't disrupted by movement/having to cast another spell.
