My Tower Got Worse after v28.3

I can't find where I changed my tower in a way that would cause this, but my T11 farming runs are ending much earlier. 9200 waves to 7700 waves. Regen specifically seems to be much worse. Health bar was rock steady at those earlier waves previously.

I was too distracted by the freezing issues the update brought me to notice at first.

Anyone else noticing differences after the update?
