For those of you that don't have mics or are unaware and spam in chat about where the spike or enemies are; you should know about valorant's very epic ping system:

Holding "," (comma) ingame:

Holding comma is obviously not easy, especially while in the middle of a gunfight; which is where holding Z comes in. This is a much more straight forward ping wheel, and can and will save you the time to spam "all a" in chat

There is also another method, which is mostly used for banter, but can be equally useful: pressing "." (period)

Pressing :"." ingame:

This one is useful for before the barrier drops: Setting up sites, flanks or having friendly banter.

Hope this helps you, and hopefully I see less spam in my iron lobbies :_)
