Ragnaros: The Affray quest not working

Hello, I'm leveling a tauren warrior, I'm level 30 and I'm trying to complete the level 30 warrior quests to unlock berserker stance. I'm on the Affray quest, which initially seemed to be working appropriately, enemies spawned when I stepped on the grate, but I failed and had to retry a few times. Eventually I figured I wasn't geared enough to do it so I left for a while, logged off, and have since came back and am trying again. However, after abandoning and retaking the quest like before, when I step on the grate nothing seems to happen. The quest timer is ticking down, but it's not spawning any enemies for me to fight. Any ideas on what might be the problem?

I encountered an issue that is almost the same as yo said. The difference is that the Affary Challengers are not spawning for me. I'm playing a level 80 warrior.

Yea i got the same problem, so are we supposed to play without Berserker stance now ? lol
