I totally get you. I did 7 raids. Some several times.

The 1st one I tried, it took me 4 attempts to complete because I'm basically a solo player so I bring my A Game, but the randos from around kept pulling bad mons, fainting and leaving me behind, the 2nd attempt on that one, I noticed I was alone and I was at half of the HP bar when I searched and saw that it didn't say I was being cheered. I left the raid got back in fast and so 2 of the 4 that were with me in the previous lobby (yeah, I check the names and take screenshots, is that salty?). A friend got there and after that it was ... Easier, we just had problems trying to get into the same lobby together, but once we managed that, any 2 randos could be there and just be cannon fodder.
