There is nothing better in Call of Duty than a brilliant comeback and there is nothing worse than throwing it away. I had a horrendous defeat on Cranked earlier where we blew a 40 point lead and after being 8-1, I finished 11-12. I noticed a few people quit on the opposition which made way for some better players who managed to turn the game on its head. Thankfully, I usually recover and not be too disheartened. Some lobbies frustrate me and I just have to get the hell outta there usually after bad misfortune continuously or the opposition being rather jammy. If i try too hard to get even, I just become sloppy and increasingly frustrated. COD is enjoyable 90% of the time but technical woes and irritating opponents and even teammates can turn joy into grief.
Sometimes I play too much and despite being tired, I keep on going and my play deteriorates which leaves me playing more as I try and salvage the session to finish on a strong note - that sometimes makes things worse as I then think I'm back in the mix and continue to play, only to fade away and then have to repeat the process and try and clock-off for the evening.
I think Call of Duty affects the majority of the community in the same way - we're all humans after all but some can just write things off but most get riled at inconsistencies and misfortune and that is all part of the experience.
