The formulas are terrible but if my understanding of them is correct, you would generally need around +300% total AS (including the amount you gain per level) to reach the 2.5 attacks per second.

This is from looking at reasonably fast champions like Master Yi, Twisted Fate, etc.

TF has a base of 0.651 0.651 + (0.651 * 300%) = 2.604
