Insurgency: Sandstorm's text chat is frustrating to use because there's always a chance that whatever you type will immediately be pushed out of the text box before it can be read by other players, either by teammate damage notifications or other players' voice commands. This would not be a problem if the text chat box contained only text chat messages. For example, Rising Storm 2 has two separate chat logs for voice commands and text chat that work like this:
Written team damage in the chat box is very annoying aswell, especially when somebody gets hit by fire. every point of damage is written down separately and Poof! gone is the message. I stopped using it completely, apart from "gg" at the end of the round. Literally no point in using it.
