Hope didn't mean that they would definitely succeed. However, after Lu Li saw hope, he started to constantly adjust everyone's positioning and reminded them how to cast their skills and position more efficiently. He used all types of methods and strategies to maximise everyone's fire resistance.

So, having everyone boost their damage output was a good way to increase their success rate. At the start, they had to be cautious, so everyone dealt damage carefully. However, now that they had seen everything Ragnaros could do, they could now focus on dealing damage.
Lu Li had grouped a lot of Berserkers and Thieves together, who would play the crucial role of damaging the boss.
