I returned to the game about a year ago after a long time away and started fresh. As I leveled, I noticed right away that many of my instances, both while leveling and later at max level on normal, heroic, and mythic 0 difficulty, did not involve much cooperative play. I was mostly just running far behind a tank, usually a demon hunter, who had much greater long-distance speed and could solo the entire instance. I wasn’t really playing the game, and I wasn’t learning my class in a meaningful way. It did not prepare me well for even low-level Mythic+ runs, and I essentially had to relearn the game from the start. It wasn’t a very good experience. Eighty levels of just running behind someone else, hardly doing anything, only to get a rude awakening once I started doing +2 keys and people were upset because I was terrible.
In the spirit of making the game more accessible for new and returning players, and giving people a fair chance to learn their class, I would suggest equalizing long-distance movement speeds between classes. I’m not saying Demon Hunters should lose their in-combat mobility that defines their flavor, but their ability to maintain such high speed over an entire instance without effort could be toned down a bit, or the baseline long-distance speed for everyone else could be increased.
In my current experience, leveling as a DPS or healer feels like being an NPC in someone else’s solo adventure. Like the NPCs in old escort quests, we move slowly while the main character runs far ahead.
I don’t mean this as a criticism of Demon Hunters or any other class. Players are simply using the tools their class provides, and the game naturally incentivizes optimization. I’m only suggesting some rebalancing to make the game more conducive to cooperative play and learning.
Also, yes, I do use the tools I have as well. Some classes keep up okay, like druids or shaman, but a mage with 2 blinks, or a warlock, many others, nope! Even worse, if you die and as is common, people don’t even rez you, you may not even make it back up to the group before the last boss is killed. (Happened to me this morning).
