I agree that a global chat is a good thing (and should be called Global instead of Side Chat). The learning curve on this game is already very high, this becomes frustrating for new players. If a new player can't figure something basic out (because lets face it the in game tutorials are junk) then they will not continue to play. For instance when I first started to play I had questions that I couldnt figure out on my own so I tried asking in chat. However I didn't know which chat was the right one to talk in. So I would end up talking in Direct Communication and get no response because no one was around me. Switching channels took a while to figure out that Side Chat was the best option, because very often even when using side chat no one would answer simply because so many people playing don't want to interact with or help a new player. Its like they are afraid of this newbie suddenly going "Oh my god I know how to switch fireing modes on my gun" and then they magically are able to kill everyone. Adding radios will NOT help the problem. In fact it will further complicate it. Because now a new player not only has to contend with not having a way of getting simple advice, but they also have to figure out that they need to find a radio in the first place and then figure out how to use it once they get it. Honestly radios should not work as a "talk to the world" type item anyway. It should instead be a "talk directly to this specific person, who also has a radio, without anyone else hearing it" type of item. So in conclusion: Global chat helps new players learn and enjoy a game. Without it fewer new players are likely to stick with the game (I said fewer, not that no one would. It is a quantitative difference) because of frustration. More new players is a good thing, fewer new players is a bad thing.
