Honestly, I see few downsides to re-adding general. While it's true that inappropriate content can be easily broadcasted to large quantities of people, local chat in a crowded area such as the grounds is basically the same effect. Unfortunately people will make fools of themselves for a cheap laugh no matter what, so I don't think the chat channel will effect much there. As for pushing people into different maps, that's not necessarily a bad thing either. While it may make it easier to break the rules for some people, which is never good, people are bound to do such things away from the public eye regardless. Dispersing the player base more may reduce lag (even my computer bugs out a bit when I go to the Grounds entrance) and reduce chat and "x has arrived" spam.
