Sometimes, there are good reasons to go afk.
The last 4 hours before server shutdown, every single pvp on my server was dominated by the same 6 man pre-made.
I don't know how they got 6 in there consistently, but they did. 5 were from one guild, plus the same extra buddy - time after time.
First few hours, I fought and lost.
But as every pvper knows, solo queue without vent vs. premade with vent is just no contest.
So the last few matches, I merrily afked in some secret hiding spot (every map has one) and did my crew skills.
I will continue to do so until Bioware makes a separate queue for premades.
Bottomline - since premades ruin solo-que, afking is justified!
