So far my favorite take is, of all things, this forum thread where the sheer volume of people reporting things as bugs that aren’t bugs, but just the way the game worked back then. I think I laughed the hardest at Warrior health regeneration is working at the expected rate, which is a very nice way of saying Yes, you’re dying a lot, that’s how it was for Warriors back then. I’ve said it before and I know I’ll say it again, but guys, all those supposed ‘dumbing down’ changes that got made between then and now were for a reason, and in a lot of cases? That reason was because it’s awful. Much of WoW Classic is going to feel like getting a sandpaper massage compared to the game as it is now — a whole host of conveniences and improvements have been made over the years.
Arms: Sharpen Blade - When activated, your next Mortal Strike will deal 15% increased damage and reduce healing taken by 50% for 6 sec. Fury: Battle Trance - You go into a trance causing you to regenerate 3% of your health and generate 5 Rage every 3 sec for 18 sec after using Raging Blow twice in a row on a target. Using Raging Blow on a new target will cancel this effect. Protection: Thunderstruck - Thunder Clap roots all targets for 1 sec. Tuning
Most people come here not to read walls of text, they look for the better-rated strategies that match their pet collections, copy&paste stuff they need to import into their addons and only come back if something goes horribly wrong and then mostly to find help in other peoples' comments who also struggled or to find a different team/strategy: I don't think many people wanna read about stuff that already happened to them, they mostly want to see solutions and it's the best way to have them in a well-optimized strategy&team already.
2. Achieving. There are many pet battling achievements in game, and following the natural trail through the Taming [Continent] achievements up to Pandaria, and then on to the Spirit Tamers, Beasts of Fable and the Celestial Tournament was an epic journey for me and for many others. It's well worth doing. The Celestial Tournament is still, IMO, the pinnacle of PvE pet battling. However, WoD and Legion and BfA have added more battling achievements.
