First of all, yes, I will be making Sla'arth and he will be out relatively soon. All I can say is, Sla'arth is very CC heavy and quite tanky while doing his job! ^_^

As for the E ability, I am pretty sure it's not common to have the CC ability on E, maybe it's you that got used to champions that used E for the CC ability? For example, 's W ability is his CC ability, same for, , , etc. It's really random to be honest, and I don't think that is planned at all.
