Good point from Dingyu - I think the phage slow is a bigger deal in many cases than crits are (whether you get a slow on that first hit might determine whether or not an opponent is able to disengage entirely). In general, the randomness of crits is mitigated by the fact that it's most relevant to ADCs, who tend to deal damage over a series of attacks rather than in one massive blow. That means that over the course of even a small encounter, you'll get a fairly predictable amount of damage from crits. Of course, if burst mages could crit you would have a much more dramatic random impact.
