I kind of know where you are coming from with the 'Bowser-curse'..
But I think it tends to work both ways..I admit sometimes you play, everything that can go wrong does go wrong..
Spawn...get spammed by a tuber...spawn... get Predatored....spawn...get shot by a Sniper using thermals from across the map..etc etc..
But on other days, things just go right for you...You spawn and someone runs right past you, so you nail em , then you lay a claymore, run round the corner and nail two people doing the 'dance of death' (3 kills), bang claymore goes off (4 kills) you easily recover your care package which turns out to be an AC-130 (lots more kills), you nail a couple more people running for cover, get your Harriers or Chopper and bingo you've practically won.
You gotta take the rough with the smooth.
