Most op things for wotlk in open world/bg

[Cresyda]

Which are the most usefull items/things for this? (We all know engineering boots, bomb AoE stun, Im looking for those strange little things that not many people know)

Something like "Magic Dust" for example, Invisibility Pot, Increased MoV Pot, some plants with snare, etc.

Anything that can give more survivality, ways to outplay (1v2, 1v3, etc). Thanks!
