It would help to think of crit as an autoattack damage amplifier, where 1% crit chance increases your autoattack damage by 1% (or 1.5% with ). Past a certain point, raw AD will increase your autoattack damage more than crit, and since you have a limited amount of inventory space you're much better off getting a mix of AD, crit and attack speed, plus other beneficial effects, instead of going for 100% crit. Another thing to consider is that while there are a lot of abilities that scale with AD, and several effects that scale with attack speed, very few abilities scale with critical strike chance, so you're sacrificing a lot more for crit than you are for any other stat.
