First things first, Modern Warfare 2 is a fantastic game, it's near perfect BUT IWnet is far from perfect, if this game had dedicated servers I'd happily have unprotected sex with it and make strange disk shaped babies.
Current problems with IWnet and MW2:
- Joining with a large party is extremely troublesome, more often then not a member of your party with get disconnected from the host, get kicked because the game is for low ping players only or countless other errors.
- If you're playing in a party and the game tries to merge lobbies there's a big chance one of your party members will be kicked.
- IWnet makes strange host choices, quite often you get stuck with a host who can't give anyone more then 3 - 4 bars (10 bar setup @ 20ms per bar)
- IWnet fails to migrate host more often then not, sometimes it says "No suitable host available" when I'm in the game able to host and keep everyone at a green ping.
- Iw4mp.exe crashes often when trying to join a game.
- The game has random lock ups, small 1 - 3 second freezes during multiplayer, many users are also reporting green, black or pink "matrix like" effects covering their screen for a few seconds.
- Users are reporting losing their multiplayer rank after a PC crash.
- Rank hack is available and working, I've seen at least 10 max prestige players so far (usually at the bottom of the scoreboard)
- Aimbot/Wallhack are currently available and undetected by VAC.
- You can't type in the lobby.
- Games often start with unbalanced teams.
- When a player leaves mid game more often then not a replacement isn't found for him so the game stays with uneven teams.
- No team balance, if your team loses a player you can expect to be outnumbered the rest of the game.
Anything I've missed?
