every time your side wins you get x1 mark if you are rank0 (recruit), x2 marks if you get 1-5 honor kills, and 3 marks if you get 5+ honor kills (rank lt). If your side loses you get 1 mark.

The easiest thing to do is join a WG when it starts, and have all your guys join one of the random raid groups. On my server a ton of people run mods that auto-invite, so I just have all 5 guys whisper the person "invite", I go hide out in the base somewhere, and automatically get ~10k honor and 3 marks after 15-20 minutes, plus a ton of stone shards from the 2-3 quests. It did take a few days to get 70 marks (boots+helm) but most of the time I was just reading email, lol
