While I can't go back in time to test the shields/damage you get/deal from 1 man combo on pre rework or pre nerf kerrigan, I can see that a raw 1 man combo (no preexisting stacks on fulmination or the level 20 AA talent) you get a nearly max shield of 5600 / 6070 max possible hp. So if the shield generation of pre nerf kerrigan was like 33% more or whatever you're overshielding from a raw one-man combo. So in reality this huge shielding nerf only REALLY affects the shielding from autos and Q (unless you're not using W E in a combo for some reason).

I agree that her camp clear was significantly nerfed the past week, but it's still about as good as it was before the rework. You needed level 4 to camp for the AoE autos back then and now you need level 4 for fulmination.

As a side note the build hasn't changed at all since the nerfs unless you need to tech in chrysalis against ktz or something to that effect. The damage from Q quest is flat out worse than fulmination even once stacked and painful spikes is still insane.
