Preface - I haven't played WoW for any length of time since quitting at the end of WotLK. I dabbled in the next few expansions, where it seemed gold was overabundant, not sure if that's what killed the gold farmers/gold bots/sellers, but I didn't seem to see any, or even think I might have a use for them. However, with WoW Classic, I can see a market for them to come back. Did Blizz ever put something in the game to eliminate this after WotLK, or was it the gold abundance that destroyed their market. If not, I see the gold sellers and websites coming back.
Finally, a clip of WoD: https://www.youtube.com/watch?v=YtKDmlNLVtE&t=5m26s This one I have petattack macroed to a button on the right-side action bar, 2nd from the top left side (icon looks like a bone bow). You can see my bird pet take off INSTANTLY when pressed. I realize this one doesn't prove much regarding Classic, but this is proof that it WAS functioning this fast until Legion. You can see the delay on Live yourself by logging into BFA.
The company has provided a list of the most commonly reported gameplay elements that Classic players are reporting as bugs, including warrior health regeneration rates, the lack of quick objectives and POI tracking on the map/minimap, the presence of a dot as the marker for completed quests on the minimap, fast running NPCs, and slow creature respawn rates (full list below).
So we asked ourselves, would it still be possible to deliver an authentic classic experience if we took our modern code, with all its back-end improvements and changes, and used it to process the Patch 1.12 game data? While that might seem counterintuitive, this would inherently include classic systems like skill ranks, old quests and terrain, talents, and so on, while later features like Transmog and Achievements would effectively not exist because they were entirely absent from the data. After weeks of R&D, experimentation, and prototyping, we were confident we could deliver the classic WoW content and gameplay without sacrificing the literally millions of hours put in to back-end development over the past 13 years.
There’s the reason why some players used to call the game World of Roguecraft. Rogue was one of the most popular classes in classic WoW and there’s a good reason for it. During vanilla, Rogues topped DPS meters in raids and dungeons, but their main strength was world PvP. Rogues could stealth through enemies avoiding unwanted engagements with the opposing faction. Additionally, a huge variety of crowd control abilities and high burst damage made them the worst nightmare for the cloth-wearing classes. However, Rogues were in a bit of disadvantage regarding end-game gearing since most of their gear pieces were useful to other in-game classes as well.
