Not eye strain, but the strobing in the 7.1 msq dungeon made me physically ill--I had to stop partway through the dungeon to go for my migraine meds, and I am categorically not going to be able to run expert roulette without a friend party that's willing to carry me through one of the bosses so I can close my eyes. If people are reaching out to journalists about eyestrain I hope the increasing flashing/strobing can be brought up too (and I'd mention it elsewhere if I knew where to mention it).
