I completely forgot that WoW doesn’t have such a thing as summoning. The only way to get somewhere is by flying.
And Blizzard are such monsters for putting in a max-level-only raid that expects you to have something available to max-level players. I can’t believe those villains would do that! What’s next?! A Level 60 raid that requires you to be Level 60?!
Incidentally, I’ll be honest and say I read the “requirement to do several raids” as “You had to do several raids to unlock it”. You should work on your writing so things aren’t so ambiguous, but I guess that’s why you keep editing so much after people respond to you. By the way, TBC also had raids that were not accessible by ground, so this isn’t Wrath exclusive.
