It's Alterac Valley weekend once again, and although you can't currently use the Alterac Valley Marks of Honor for anything other than old world rewards right now, the Battleground still remains one of the best places to farm Honor. In case you're hitting up the frozen valley this weekend, here's a handy guide that should help you through the Achievements you need to get Master of Alterac Valley.
Alterac Valley Veteran
Win 100 games. I don't know about you, but I personally don't enjoy Alterac Valley enough to slog through the number of games required to win 100 times. That's probably because of my Battlegroup, where I find myself losing more than I win. Like all veteran Achievements, this really is just a matter of time, and the only real problem is finding yourself on the losing faction -- which tends to be a trend in many Battlegroups unlike other maps, which are largely symmetrical. Alterac Valley is asymmetrical, so a Battlegroup with a faction that knows how to take advantage of the asymmetry will tend to win most of the time. I'll peg this one at hard, and I think some of you will agree.
Alterac Grave Robber
This is ridiculously easy because it doesn't require you to actually capture or convert the flag, just tag it. During the course of one game, there'll be many opportunities for you to do so. Snowfall Graveyard, the uncontrolled graveyard at the start of the game, is an excellent target that can be taken over and over.
