I've been both on the receiving and giving end of this. Sure it's annoying when you're up against someone who should be way higher. But in the end, it just comes down to bad game design.

I, for one dropped after losing 4 games in a row, win 1 for a 15 min incubator, then lost another 6 in a low. Pretty much entirely just because I had a string of bad RNG luck. I don't want to spend 30-45 mins battling just to get a 3 hour incubator going. So I drop trophies.

The way I see it, it's 1 extra annoying game for the other person which I can sympathize with having been on the other end, but I avoid the extremely frustrating situation mentioned above.

Tl;Dr: Games like this are supposed to be fun, not frustrating. Don't hate the player, hate the game.
