【Braum Armor is missing!!】

Your official page "Braum" Armor: 26.72 (+4.5 per level)

but now in game
lv 1 26.72 armor (+3.X?)
lv 2 30 armor (+3)
lv 3 33 armor (+4)
lv 4 37 armor (+4)
lv 5 41 armor (+3)
lv 6 44 armor (+3)

if normal add (+4.5 per level) lv 1 26.72 armor (+4.5) lv 2 31.22 armor (+4.5) lv 3 35.72 armor (+4.5) lv 4 40.22 armor (+4.5) lv 5 44.72 armor (+4.5) lv 6 49.22 armor (+4.5)

Can you tell me why? in game and your official page saying It is not the same? I dot see any nerf about "Braum" Armor per level? Every time he level UP he is not receive +4.5armor

Im sorry my English is not very good……… i hope is a BUG thank you！
