do you think every time i have to play ORLY (top 100 player) at my melee weekly i just resign it away? no, i get excited because i get to see how better i've become since the last time, i get to see how he plays and adapts. same thing here.
another thing: whenever there's some sort of prize on the line of course top players will be playing. faceit isn't really meant as a platform where you can just get friends together and dick around, nor is it really meant to introduce players to competitive. it's somewhere inbetween TF2Center and ESEA; not really a league, but not just a super pick-up-and-play experience.
also, faceit has ranks and such so things like this should iron out over time anyway
