Look man Sirzechs was born abnormal as well talented with a mutation that make him the monster that he is now, even at Rias age he was dominating mau class opponents like nothing. has Rias done something similar? No, even know she would get bodied by a mau class opponent.

"Will she surpass Sirzechs...ask in 500-600 years when she is the Age that Sirzechs is now ;)"

So you think that Rias by herself will be able to stand against Sirzechs,Ajuka,Ddraig,Albion,Chrom,Typhon,Fenrir,Indra in 500 years?

yeah no, she's talented but like i said not in the realm of special like Issei or Vali.
