Cassiopeia's new passive is unrealistic to max out in Dominion
Given that the passive takes an exceptionally long time to max out, and doesn't give you extra stacks for poisoning multiple Champions at once, I find that in Dominion the only way to reach 400 stacks is to... actually, there's no way.
Can you give Cassiopeia Dom-specific changes so she can realistically max out her passive? Maybe a lower stack requirement?
