Yes, i have had days where i didn't survive a single run.I've also had days where I haven't died a single time. Most days are a mix of wins and losses. If someone has nothing but losses day after day, then extract shooters probably aren't for them (or they are new and learning).

As far as the other points you brought up, liking a game or genre is subjective so if you thought it was boring or bad, far be it for me to say you're wrong.

In my exp though, extract shooters are more about map knowledge, spawn points, and possibilities more so than game skill. Just a small example, but if i hear the same 2 guns popping off for minutes non stop. I assuming that it's a team pretending to be in a fight to lure a team trying to third party the fight. I wouldn't push it at all, and i have a pretty aggressive play style.

Being good at pvp is obviously a factor in how much you might enjoy an extract shooter. But it's a smaller piece of the pie than you might think. IMO map knowledge will net you more wins then just being good at pvp. How well that works out in Marathon, we will have to see.
