I generally don't lurk but will attack in heroic of opportunity allows. Lurking at lower heroics only brings peeps I can't attack because of my lvl (59 now), and lurking at higher heroics brings peeps who can kill me quick. So.... not doing it much anymore. But in beginner stages it can be a good source of coin, creds and rep.

Just remember to not go afk, or someone will get you first. And don't challenge heroic and claim rewards or you can't lurk there til next day. Below stairs is a good place to sit and watch for prey. Or in far rt corner of ring in heroics you can't beat yet. In ring for heroics you can beat, heroic will always engage battle if you try to just sit there. Lol! Takes time to learn the tricks, but when you do at lower levels this one can help you alot. Same with hanging out in wilds after grinding.

Just remember to be alert when you go to grind in wilds, do Heavens palace or heroic realms. Get familiar with who is around you in arena and leaderboard ranks and try to find out who you can kill and who can kill you. In attacks, you can't check other player's equipment, only attack. But if you know who can kill you an see them in these areas, hit refresh fast or back to get out before they can attack you. Not much you can do though if you get attacked when in the middle of a battle.

Hope that helps some @OP.
