Yeah.. just got the same email. The fact it went straight to my junk folder instead of my inbox like the rest of the GW2/Arena emails do sent up a red flag immediately.
The look-alikes can be pretty convincing, got to look out for wording. Also good to come check the official site separately. I get similar emails, even for games I don’t play, but this one was surprisingly more realistic than the others tend to be. Stay net-safe, friends.
