Shaper fight (maven witnessed)

Hi,

i just did my first non-uber shaper of the league and also had maven witness on.

During the phase in which shaper spawned mobs and you need to protect Zana the maven very quickly spawned a clone of Shaper, which killed zana with his beam. I dont remember this happening before. Is this intended?

I also managed to get zana to shield me once, but again the maven spawned a shaper clone way faster than i can remember from previous leagues. (before shaper even started shooting black balls)
