I don't see how you can stan a videogame company tbh, unless i guess that involves going to events and buying a lot of memorabilia, none of which i'm interested in
i will say that before WoW ebola infected the company Blizzard was the GAWD for me though, and same with Capcom before they started releasing remakes over and over and over again
WoW didn't ruin shit. If anything it shined a light on some really good developers at Blizzard, specifically the raid creators for vanilla and BC WoW who created some truly amazing gameplay. It's hard to take WoW hate seriously from people who didn't do raids at that time. The game is repetitive and boring now, but back then those raids were the real deal.
Blizzard has been ruined by losing talent. Many of the guys who made StarCraft 1, Brood War, D2, WCII, and early WoW etc great are no longer at the company. What has followed is a rather casual approach to design. Anyone could play and have fun with those classic games, but the skill ceiling was high. So one player could have a blast casually playing Big Game Hunter maps in Brood War while a professional player could play the game at its highest skill levels, making 200+ actions per minute.
SC2 relies less on micro and more on simply attack-moving big units who do major damage. Current WoW rehashes a variety of old boss techniques and design. D3 is...well, D3.
Another issue is the way Blizzard hides important game mechanics behind what are essentially pay walls. BNet had more features in 2000 than it does right now - and Blizzard has decided to "update" it with each expansion of a game. So the first SC2 expansion featured various online improvements over the standalone that SHOULD have launched with the standalone. And the next expansion will add in even more improvements that should have been out years ago. Likewise it took D3 nearly forever to get rid of the auction house despite universal complaints.
