Mic isn't required, I completed it on hard even with a few people not talking. We use party chat mainly because you're still able to talk when you dc in game, but tbh I never had problem of game sound being too high when talking (whenever I get people in my fireteam I actually almost don't hear any game sound anymore, settings/options is your friend here). We all talk during raid and we all call out where oracles and stuff spawn. It's not a strike ofc it's not it's a raid ... but it can be completed it little over an hour I think a group even made it in 40 minutes or something (on normal that is). We never use invisibility on the Gorgons don't even know why the hunters need to use it, it's not like it's hard, and after a bit you just know the route they follow out of your head... and it's a raid, people should read tactics and know what they are doing. Most of your points don't really make any sense, the one thing you must do though is get/find a clan if you don't have one and don't randomly invite people in the tower and add them to friend list. It's stupid to enter the raid with strangers, I've only done the raid with clan members and friends and never we had any issues (my first time I did it I was even not sure on all tactics and we beat it in less then 2 hours). No need to put it up so high, everybody should try the VoG as soon as they are 27 (or get carried by their clan if they are below). The raid is a fun experience and it's surprisingly easy, only hard mode is quite hard.
