Critical strike chance is a useless stat if you don't build towards it by getting more crit chance and more Attack Damage. Tanks don't do that, so it doesn't make sense to have critical strike chance on a tank-oriented item. Tanks do autoattack though, especially those which have passives that interact with their autoattacks. Braum is an example of this.

I just want to point out that I'm not trying to make Atma's Impaler awesome, OP, or even a top pick on every tank. I am trying to make it viable in today's metagame. Atma's Impaler isn't relevant anymore, and I think changing crit chance to attack speed will make it relevant again.

I appreciate your feedback though! It's just a concept I was thinking about at work today.
