There is a trick to momentous. Exploit the two tunnels. A lot of players take the upper one. But the lower tunnel is amazing. You can shotgun people running to the spark. Toss nades into the upper, or rift tunnel (twin lightning and trip mines grenades clean up), from the door frame... even go invis while covered, than steal the rift.

Momento has the most awkward angles and too many things to get stuck on. I liken it to being on the airplane, stuck in the middle seat, with a sweaty guy with BO who takes up all the space and has his elbows jammed into my ribs, breathes really loud, puts down his table, hooks in his headphones, has a laptop on it playing beastiality porn and touched himself (while his elbows are still jammed into my ribs). And when I need to go to the bathroom, I have to navigate out while this guy shrinks his legs, make sure not to trip on his headphone wire, or spills his glass of orange juice on his table, dodge his cumshots, and when I get back to my seat has to repeat the process. Needless to say I frickin hate that map.

That's quite descriptive, lol.
