Want to bet its the in game voip? A lot of games expose your IP when you use voip. Once they have that it wouldn't be super had to fuck with you. I'd disable in game voip if you're running into that often.
Blizzard does not expose your IP when you use in-game VoIP. There was a good YouTube video that looked at the networking in the game including tick rate, VoIP connections, etc.
Don't watch to play Support and Tank just yet because the team relies on them more for teamwork and I know I'll fuck it up right now.
I wouldn't fret too much over playing them. The hardest thing is that Blizzard uses rather generic names for their classes (e.g. "Tank"), but they don't all play in a standard fashion that goes along with that class. For example, D.Va has a ton of health, which means she can take more damage than most heroes, but apart from Defense Matrix (absorbs any incoming projectile/shot from in a frontal cone), she can't really "tank" damage. Her role tends to be more about backline disruption and area clearing with her ultimate.
While this may sound complicated, the same is true for most characters in the game. Essentially, characters just don't really play alike, and the hard part is learning what makes each character unique and how to properly use that.
Needs more maps, and honestly the biggest problem is there is literaly no sense of community in this. I feel like I'm playing a solo player AI bot game.
While the game lacks clans/guilds, closed beta did feel a lot more like a community given its far smaller player base. It was
a lot like what vanilla WoW was compared to what it is today -- far less people, so you tended to get to know each other. I'd say at least half of my Battle.Net friends list is people that I met during closed beta.
I can say that one thing that has disappointed me so far is the complete and utter lack of players using voice chat. I was playing with a friend of mine last night, and I swapped to Team Chat to find that I was the only one in there. :\ I proceeded to swap back to Group Chat and just talk in there instead.
