Halo Infinite Multiplayer/Customization

Three Things I’d like to cover, The one and only issue that I have with PvP is the no player collision. I don’t mind it with your allies but with the enemy player it starts to become annoying. Multiple times to to melee an enemy play in the back and they just walk backwards through you then back slap you should not be a thing or when your in a gun fight then slide into each other instead of stoping and fighting it out you instead slide through each other and then would have to turn around. I have seen players start to exploit this and it’s only day 1. I’d also like to have player collision because that’s old school Halo especially for custom games. Two, now we all don’t like the battle pass progression so I won’t go into it much but what I would like to see is just adding base experience just for playing a match I know this will fix the slow progression in the battle pass. Finally three customizations, I love the customization so far but the only thing I would like to see is adding multiple attachments options on the helmets (left/right/top) like Halo Reach where you could have 2 or 3 attachments on your helmet and on the vehicles so you can have every part of the vehicle customization appearance on at the same time. But these are just my 3 cents that I’d like to see changed.
