I finally finished the Battlefield Barrens weekly quest and got my Hordebreaker title. I am not sure if I liked the process or not.
When I started the quest, I saw that you needed 150 of each commodity, and mobs were dropping only 1 commodity per mob, so I gave up rather quickly. Not to mention that early on it was pretty buggy because of phasing or cross-realm zones.
But today I decided to just finish the weekly, and actually got a bit caught up in it. It was fun killing orcs until a champion spawned, and then flying from champion to champion. Or escorting a random caravan every so often.
It felt very old-school, this farming. No quests, no rigid guide-rail to hold your hand. I think it would have been very nice in a small group. Trying to heal while I was solo was a bit annoying.
I don't think I'd want to do this all the time, but doing it once was an interesting change of pace.
I did like the way the rewards were structured. You do it once, and you get a pet. If you like farming, you can farm more and get gear or other items.
