It's cool, I've only done PvP a couple of times, not really my cup of tea either (although lately I've been considering giving it a bit more serious try, if only to do some of those exotic bounties). Honestly, in voice chat in games like this, the less talkative you are, the less likely you are to get booted, as long as you're giving your gameplay your best effort. Unfortunately, the whole 'being invited at random' thing is frequently hit-or-miss. If it's a group of 31s and 32s looking to fill the last spot in the fireteam, or if said group is shorthanded, and maybe needs a warlock to cheese that one part in CE, for example, they're gonna kick you immediately. Now, the POLITE thing to do would be to explain all that BEFORE they kick you, but at that point you run into the whole "anonymity of the internet" thing, and when you combine teenaged gamers with a limited playtime, courtesy can go out the window pretty quick (no offense to y'all, but I was one of you once, and I'm just as guilty as the next guy. Of course, back then, WE DIDN'T HAVE INTERNET, so it's a whole different ballgame. Just sayin' :3). Don't let being kicked discourage you, though! There's no penalty for it, and it's not like you can develop a bad reputation or anything. This is where the "anonymity of the internet" actually works for you. The only one who's gonna lose sleep over being kicked from a raid in a video game is you, and trust me, you shouldn't be losing sleep over it either. Just keep giving it another go, it may suck hard initially, but patience will be rewarded with an awesome raiding experience! :D
