Campaign input lag and please add matchmaking

I know this has been posted and complained about for years now… but PLEASE 343 fix the co OP campaign. I live out of state from my brother and dad, and we grew up playing halo together and just want to be able to play without the lag being so bad its unbearabl . We have tried multiple times to play and after 5 minutes it just becomes to frustrating. Also once (if ever) this issue is fixed, I know ALOT of people would love the option to search for other players for any campaigns. I know there’s the looking for group option but an actual integrated search in game would be nice too. Please make every one happy and at least fix the input lag. I know kany players (myself included) plan to beat the whole campaign all the way through before the release of infinite. Please make your customers happy please.
