I never played Wrath because it was always terrible. And this is proven by the fact that player growth stagnated in Wrath compared to TBC or Vanilla.
And people socialize during downtime. Not all people. But would you be here on this forum replying to my post if you had work to do? A dungeon to finish? No. You probably posted this because you had down time.
I’m not even asking for a lot of downtime.
Something I forgot to mention but it’s important that Blizzard makes sure Dungeons aren’t too difficult for both factions to reach. Shouldn’t take more than 10 minutes for enough players to get there to start summoning.
