It was the Right Thing to do in buying Modern Warfare 2. You get real good at a loadout and then the game changes it up. Either something unlocked (a game mode, an attachment, etc) or the game gives you something in terms of perks or ranks.
The sad part is there’s some semi-annoying glitches out there. The original was the javelin missile glitch where a player could hit themselves with the missile and walk around with the unspawned missile attached to them. If you kill this player you get blown up. While it does nothing for their K/D ratio, it was really annoying to have someone suicide bomb your defense. They patched this with the last update, and it’s now hilarious to spectate someone trying to do it. The other patch fixes the care package – it no longer kills you if it falls on you and can’t be used as a bridge anymore.
The newest problem pissing me off is the Public Private Match. You choose a game mode, you go to enter with friends and you end up sucked into someone elses game mode where it’s totally different. Also it’s FFA rules despite being a “team game” and you gain XP killing teammates. The upside is when you’re sucked in, you can choose “END MATCH” and kick everyone out which I find hilarious since it’s fairly tempramental to start these things. If you select END MATCH and you’re on the winning team, you gain a ton of XP. If you’re on the losing team, you still gain some XP, but either way you’ve gotten the XP playing for all of two seconds.
