343 need to fix halo 4

Halo 4 is an awesome game, maybe one of the best but…
There are far too many bugs still in the game that im surprised that they haven’t been fixed.
It’s getting to a point where people are really starting to see these bugs and it is affecting the game. All 343 needed to do is release a beta so all of this could of been avoided but no they rushed it.
For example there is still the black screen everytime someone enters/leaves the game, sometimes it wont give me a loadout or sprint, still being shot through walls and as i was assassinating someone they managed to get out of it, turn around and double punched me whilst i freaked out.
Now im not being funny but they seem to me that they were the same problems in reach yet nothing has been done about it and we want answers.
Also recently i’ve noticed that searching for games has been messing up.
Sometimes clicking on a gametype doesn’t work or when partied up with friends it splits us up into different games or disconnects us from live.
It just feels like im on happy wars (brilliant game but horible to find/be in a game).
Im not trash talking halo 4 just trying to get 343 to see whats happening and to fix their noobish mistakes…I didn’t pay £70 for a game that should not of passed testing.
