Something like Blade Ward?
I pretty sure we can all agree that Accuracy is just flat out lame compared to Mongoose and Executioner.
I dont know why people even bother with it even if they do have the gold, it gives less hit rating then a Weapon Chain in exchange for some measly crit rating which I could really do without. Titansguard was rather boring also though.
Mongoose procing was so exciting back in the day, especially when it proc'd along with my Aldor Trinket, Pocket Watch, and MgT Trinket. (Crush THIS Tidewalker!!)
Blade Ward is great for 3 out of 4 tanks. Still leaves Druids in the dark but I am sure Blizzard will be making a Druid enchant in 3.2.
