Playing around a 20% proc chance might seem silly, but it's all about efficiency, getting a quickened aetherflow proc at 3 sec left on your AF CD is just a big waste.
Beyond silly. A lot can happen in 30s, and you need those stacks on hand all the time just in case. Even if I have Aetherflow off CD I still won't waste stacks, a time may come where I'm forced to pop multiple Lustrates and I'd rather have the Aetherflow ready. If anything, that trait needs to make Aetherflow 45s guaranteed 60s. That alone would be a massive QoL change for SCH (though making Indom a 1s cooldown like Lustrate would really help too).
