The problem you're addressing still lies with the duration: at a 3.6 second cooldown, a 2.5 second duration means it has 69% uptime, which is why it's overwhelmingly strong. A 1.5 second duration gives it 42% uptime, which would help curb its strength. Effectively, Riven will spend more time with her shield down, which is what would help against her. Increasing the cooldown indirectly nerfs her mobility and her passive -- not necessarily a bad thing, but not the most efficient way of addressing the issues raised by her shield.
