Problem? Astral Eudemon?

I see that other pets have a reborn limit of 500000 but I've notice mine astral pet like TaurusMars, VirgoSachi, AriesMuba and i'm convince this is the same with other astral pet(except astral mount I think because like my AquariusCoral they have 500000 reborn limit) only have a reborn limit of 1500 only... why this? I've calculated, if it is only 1500, if so I can't make it to max star (3100*) then... could you say or do something about this, maybe open the limit to 500000 too
