FTL can be mad frustrating when the game just decides to fuck you over with this nightmare ship out of nowhere that boards you, instagibs your shields with 50 missle launchers leaving you over to the 4 shot Burst Laser to destroy you since you have no shields.
It's still fun because of the perma-death i think. Desperately trying to get the engines and/or weapons back online so you can jump out before you die is made more dramatic when you can't just say "oops, guess i'll just reload a save!"
Also winning a LoL game with a badass comeback is amazing. Frustrating since your team is likely raging and sending 50 surrender votes but still awesome. Just last game, their Kha'Zix was 17/3, the friend I was Skyping with was feeding the Gragas mid, our Fiddlesticks was more like Feedlesticks and our bot lane with me as Caitlyn was winning but only in farm and lane control.
I got all UMVC3-ish with my NEVER GIVE UP's. I've got too good of a match history to let it be tarnished with another defeat.
If I was playing anyone but Cait we would have lost I think. She has to be the hardest carry to focus with her slow that is also a pushback, her traps plus her insane autoattack range means you can plink away from the very back and relocate when they try to burst you.
I will say later on that I was permanently on full health in most teamfights. The focus... That focus.
