I'm still a relatively new player, and while I've dabbled in WvW out of curiosity, I'm very curious about something I've seen in WvW matches recently. I purposefully didn't post this in the WvW section as I suspect it will do nothing but attract vitriolic statements.
I gave WvW a run just to see what it was about. I quickly discovered it was a fast way to bang out the daily, and 2g per day is something I enjoy. I do whatever I can to help, be it building / manning fortifications, or joining a zerg or even small roaming group.
But this past week, I've come across something repeatedly: as the enemy zerg approaches, the ground gets covered by dozens and dozens of red circles, even before my Ranger w/ LB can target someone. The circles spread life a flood, often faster than I can outrun, which usually ends up with me dying.
As my team re-forms and heads out, without fail, that zerg will re-appear, and just demolish my entire force in the same fashion.
I see a lot of comments in chat about Necros and Scourge. I'm genuinely curious here: what is happening?
