Do you get better drop rates for solo runs?

I'm reffering to the infamous meat shields. I have no concrete evidence to support this, but I seem to get (good)rare drops on a more frequent basis when I venture out alone. Is this true or am I just imagining it?

Probably imagining it, though solo ONLINE runs are more profitable than offline runs no matter what in regards to finding rares. I consistently get more 6* commons and the offhand 7* commons in online solo than I do in offline, even in the SH ET.
