Personally ... I never GG. Well ... very very VERY rarely. If someone really comes up with a cool or original deck instead of playing the same 6 cards over and over that some streamer came up with, then I might give one - win or lose - just because they showed me something different ... So that's almost never. At this point though, people pretty much have all the cards they want or need anyway, so they're not going to miss a few more scraps.
Couldn't agree more!
This is kind of the attitude I take now too. But to be honest,
most players don't give GG if they lose badly, it's nothing to do with originality of decks, as to whether I receive a GG on ranked anyway.
Here's an example, I played the ST harmony tier 1 net deck between ranks 5 and 7, as I wanted to see why everyone was playing netdecks. This deck alongside poison ball variants is played by absolutely everyone, and has around an 80+% win rate for me anyway. And yet I nearly always received a GG.
Why?
Because it gives the false impression to the opponent, through the back and forth, that they actually have a chance of winning. 80% win rates suggests this is an illusion. But perhaps it is a "fun" loss for them.
Compare this to my custom MO insects deck. I'm playing this almost exclusively rank 2 and 3. It's got about a 60% win rate. When I win, I win big and can quite easily 2:0 netdecks. And when I lose, I lose big. This is a deck I made myself, there might be elements that are similar to other decks out there, but it's pretty obviously a custom deck. (Admittedly as it is an MO insect deck my options for interacting with the opponent's side of the board is limited, this might reduce the "fun" level for them)
Even so, you would think I would receive more GGs than the tier 1 Harmony netdeck,
right?...Nope.
The result, I receive GG when I lose big, and no GG when I win big.
My conclusion, most ranked players are sore losers.
