I did, and no, I'm not convinced. Conditional coverage (ie proc) and accumulative coverage (ie armor, magic resistance) are not equivalent, one always reduces damage, and the other reduces it part of the time (ever have a point of armor fail to reduce a sum of damage? no?). Further, when conditional coverage is countered, its effectiveness drops to 0. When accumulative coverage is countered, its effectiveness drops, but not to 0, given the ceiling can be raised with stackable armor/mr from items and levels. Evasion's ceiling is fixed, and its counter drops the ceiling to 0 regardless of how high it is. While its fruits are sweeter, its pitfalls are accordingly deeper, an AC is reliable damage mitigation no matter what. If you have the headroom for less reliable protection and a lot more attack speed, then rock on. Each fill their niche adequately.
Even if I understand your position, what do you think about getting AC on heroes like Naix, DK and Sven? DK and Sven have high armor themselves and i would rather have high attack speed to maximize the damage I can do while raged.
