There's this weird misconception where people seem to think you only have the right to complain about a class if it's top tier or really competitive. Really you can complain about whatever you want to - who cares? Granted it does get grating, and 5 new threads per day where people are complaining about the same things gets frustrating, but it's pretty harmless. We all complain sometimes.
Now that Palm Reading has been around for a bit, and Animal Companion is out of Standard, I think we could move on to "always Palm Reading". Not a complaint, it rarely turns out to be a problem, but I can maybe count on my hand the number of Priests I've played against that didn't play Palm Reading by turn 3 since it released. Pretty crazy - but that's just my singular experience.
Let Priest be good. While it is my least favorite class, every class should have its time in the sun regularly. They specifically are usually pretty low winrate in lower ranks, getting better the higher you go - and go long times between really competitive lists.
My issue with Priest isn't really with a card or anything, Priest wastes my time lol. I would just auto-concede but they always trick me into a false sense of "I can end this before they really pop off" and I almost never do haha. Oh well! My comeuppance for something in a past life perhaps.
