I wasn't referring to me since I didn't disclosed or said "I" I think, those two messages were referring to the average player; they're directed to them to "help" a bit, perhaps? personally I don't auto at all in union/raid events but the last time I was being serious in one and using my main team I recall being able to solo up to Lv 164 Ultimates (In the last event, I've been without my phone during this and my pc is too shitty to even consider raiding here)
I don't think it's the lazy way or something along those lines, I'm just not a multitasking guy myself and I genuinely enjoy killing bosses in this game but I get where you're coming from
