Yep. I ended my subscription to World of Warcraft. My fanfiction and favorite lore is still Warcraft, but...dang, what a difference between that and Heroes of the Storm.
i must be fair; I don't want this to be another crotchety returning player rage quitting. That isn't it. I played WoW vanilla just after it went live, so obviously when I returned for Warlords of Draenor, the game seemed vastly improved. Especially because, in the interim, I didn't play many video games at all.
But WoW hasn't aged well. If you've played Heroes of the Storm, then you know what I mean without elaboration. If you haven't played it, what's wrong with you? The basic version is free.
That being said, I've been a Warcraft fan since the first one came out in the early 90s (I'm old enough to be the father of most current WoW players). My brother and I still bond over catch phrases from Warcraft 1. But after trying Heroes of the Storm, I just can't justify paying for WoW anymore. I'll pay for extra features in HotS because the money is deserved on Blizzard's part, though.
maybe I'll describe details of my experience as someone who's been a fan of Blizzard for as long as Chris Metzen has had a job there, by for now, I'm too busy having my mind blown.
