CoD 4 Map pack

Infinity Ward recently released a new set of maps for Call of Duty 4, and I have heard nothing but good things about them.
However, Infinity Ward really should iron out a few kinks before they do anything else. Nothing a small patch wouldn't fix, but they are niggling little bastards.
No 1: Make sniping more accurate: It sounds kiinda obvious, but five times out of fifteen when you snipe someone, the bullet won't kill them. It probably won't hit or even wing them. That's just when you're stationary. It's ten times worse when you're moving.
What IW can do: Fix the damn headshots. It's not that difficult, and would make hiding in a ghillie suit and picking off the peons all that much more satisfying. What's the point in having an edge like a sniper rifle when you can't properly use it?
No 2: Please just change the server when the host leaves. There's nothing more annoying than building up a massive lead and throwing it all away when the host leaves. If Gay-lo can do it (all credit to Bungie but the game is the most over-hyped piece of average shit about) then surely CoD can.

That's the most important two things I can think of, for now anyway, and the last patch dramatically improved things by adding a mute button to shut up English pricks (surprisingly the merry old English are more arrogant on CoD, not the Americans) so get the lead out Infinity Ward, and make a good multiplayer experience even better!
