Just something I stumbled upon just now, apologies if it's been posted before, but my searches turned up nothing.
As you might guess I play Mesmer, I use Arcane Thievery frequently in PvP and usually carry it with me in PvE as well.
Some mobs have long duration buffs that can be stolen, i'll use the basilisks in Orvanic Shore (Sparkfly Fen) as an example.
They have a buff that damages and causes the weakness debuff to nearby foes, I can steal this using Arcane Thievery and then buff other players with it using Signet of Inspiration. The buff lasts for 9 hours.
So, my question... is it supposed to be working like this?
