It deals more damage, can crit and give an instant gap closer instead a kiteable walk up. You think that is worse?

For the damage calculation: Lets assume Garen has 100 base AD and 100 bonus AD.

Original Q: base dmg + (base AD + bonus AD) * Ratio

New Q: base dmg + base AD + bonus AD + bonus AD * Ratio.

So we got this numbers:

Original: 90 + (100 + 100) * 1.4 = 370

New: 90 + 100 + 100 + 100 * 0.7 = 430
