I think it's justified for those people who devote a lot of time to this game to be frustrated when things aren't going well, especially when you've been playing a long time and know how it works, more or less.
What it does is make you question the point of spending time on the game that could be used elsewhere when you don't get the results. I think blips are quite common, but if you don't see other teams having similar issues it makes you wonder why.
The season is young so there's a long way to go yet. Perhaps it will even out in the end!
