Hi, I don't know how common is this, but today I found a player with 4 additional alternate accounts on WvW for the extra pip.
He/She, with his main account was tagged up and the other 4 accounts where joined to the squad. He had the 4 accounts running endlessly to the walls with a bot/macro/whatsoever and with his main account was just recaping closest supply campaments to always be with tier X participation. With that way, he was earning an extra pip, not much I know, but he was occupying the spot for 4 players more.
It was pretty obvious he was doing that, because just after reporting this on team chat, he suddenly untagged and the 4 "afk" accounts closed simultaneously.
So now I wonder, is that even "legal", and how often do you find cases like this on WvW lately?
