500 years in the future, the mobs in F4 are angry about 5 Healer becoming the meta. Upon five healers entering Thorns arena, everyone leaves the arena while spamming "Nerf Healer!" and the battle ends there. Livid acts like Thorn died, which leads to the Sadan is Pat's and Rick's brother theory.
That's 500 years later. For now, we need a Healer Buff.
