I had the same opinion at you at the start, but then I changed my mind.

+25/50 AD, +25/50% AS, +15/30% Apen

If you think about it, the normal passives are quite useful but doesn't really add up to that much, especially since he is a melee champion. When he ults it is only for 7 seconds. Leon doesn't have much mobility so he would be very weak to anyone who can kite him. His passive also does not grant MR so he would get destroyed by APs unless he builds tanky, which would then lower his damage potential. He's not like a Riven who can just build a BT and have both damage and a powerful shield.
