Rudra was extremely nervous while heading towards the fields of thunder . He knew in his heart that he did not want to choose mediocracy, however should he fail to ascend to tier 4 on his first try , he would loose the opportunity to become a mythic class.
Rudra did not even know that mythic class existed in Omega , or a pathway to obtaining them , as no information regarding such classes was ever made public.
Everyone who stood at the pinnacle of Omega in the second phase of the game before his death , were all the players who managed to get the legendary class at tier 4.
Tier 4 was the real distinguisher between the talented and the ordinary as while people always managed to somehow promote to tier 3 after failing multiple times , tier 4 was not the same.
