Okay i got it working, sorry about the double post..

This is how i did to remove all tier 2 weapons from left 4 dead 2 and replace with tier 1 weapons (for future search)

Example, replacing spawn points of tier 2 shotgun with a shotgun chrome spawn:

modify:
{
    match:
    {
    "weapon_selection" "tier2_shotgun"
    }
    replace:
    {
    "classname" "weapon_shotgun_chrome_spawn"
    }
}

Weapon selection is listed here:
https://developer.valvesoftware.com/wiki/Weapon_spawn
need to be used with "weapon_selection", this is mostly the weapons that spawn on safe rooms..

Individual weapons can be replaced using classname insted of weapon_selection, theres a list for that too:

I uploaded my global_filters, i think i got it all cover..
