Stuff I’m mad about:
1 - Season 3 Shadowlands BM tier set. Us throughout ptr, “hey this tier set adds absolutely nothing to aoe while sv is getting + 80% to an uncapped aoe, can we get some aoe?” crickets until season 3 hit at which point our m+ numbers dropped and a dev came to our forum to promise that despite us running out of time, they were totally gonna fix our aoe. After several weeks, they did… by extending our beast cleave window by six seconds, meaning our pathetic aoe could be pathetic for longer.
2 - Sentinel owl. hunters across the player spectrum, from WF raiders to multi-glads to World Quest Wendies, again and again in the beta thread: hunter has no relevant raid utility and limited survivability. we haven’t really been compensated for the loss of our SL conduits. our single heal isn’t really much help against sustained rot damage which is the raid/high key MO these days. the devs: “we totally hear you! anyway here’s sentinel owl, which solves 0 of these problems. You may also have one more single heal on a very long CD, locked to a single pet, so RIP group bloodlusters lol. We are so on the ball.”
3 - hunter family ability locking. we asked in beta why we can’t choose pet families. watermist put up a really thoughtful and detailed post on the community council forums. the response? we can’t choose pet families because it might upset arena players who won’t immediately be able to tell whether your pet has fortitude of the bear or master’s call and might have to gasp improvise. 
4 - the double tap fiasco. i’ve already nerd-raged about this across the forums but honestly, the absolute refusal to engage or explain themselves just comes across as spiteful. really? we’re not even worth a single one-sentence explanation in the patch notes? honestly i get it if they they were scared of hunters being mean to them on the internet (valid tbh, nobody likes being the lightning rod for decisions that are unpopular with customers) but they couldn’t even drop a note to mispelled on the community council forums or stick an explanation in the patch notes? now we’ve got pve hunters blaming pvp hunters and pvp hunters getting mad because they’re tired of being blamed for something that disproportionately damages them and nobody’s happy, except i guess that one bad unholy DK player who got ganked in a bg and spent all of ptr whining about it.
