Let’s just say that compared to Vanilla, Classic takes very little time.
Now, it’s a 15 year old game and everything is known. So it will obviously be speed run. But at least give the raids some dignity and have the bosses engage some of their limited mechanics. Instead they’re training dummies.
Also regarding time, bosses took longer to die. dungeon runs were longer. This had huge impacts from guild dynamics, to BiS, to player burnout. As one poster commented, “Additional time is nothing but tedious.” But things being tedious has huge impact.
Things were already straight forward in Vanilla. But in Classic they made things face roll and ridiculously accessible.
