Her ratios may not be outstanding 1vs1, but they are huge in a team fight. Especially her W. It has a maximum of 100% + 80% + 64% + 51.2% + 40.1% = 335.3% total ad ratio per 3 seconds. In the best case that's 111.76% total ad per second. With 40% cdr, you'll have a 335.3% total ad ratio per 1.8 seconds, which results in 186.28% total ad per second. That's an increase of 66% in AoE damage, which is massive.

What you want to do as cdr Sivir is stack ad, cdr and armor penetration. A sample build would be:

1. Ionian Boots of Lucidity

2. Bloodthirster

3. Black Cleaver

4. Zephyr

5. Infinity Edge if they stack hp/Last Whisper if they stack armor

6. Frozen Mallet/Warmogs/Guardian Angel/Runic Bulwark

Get the missing %cdr through masteries and runes.

It's a very effective niche build, that works best if the enemy team is rather short ranged (so they clump up more). If they run something like Lux, Xerath, Kog'Maw you won't do a lot of damage with it. It also gets shut down by Silences (mainly Malzahar, Soraka, Cho'Gath), although they Spell Shield helps somewhat.
