Most likely. Imagine it'll be in the same grouping as Sandspin and Infrasonic's -EVA effect.
That said, I'm really wishing SE would give us native buff duration traits to the point where casting one spell on someone could have it lasting 15 minutes. Even better if this is achieved without needing the Emp set bonus to Composure. Over time, BRD has hit the point where its AoE buffs last a very decent period of time, ultimately leaving them more time to tend to other support duties or even melee. Cast lock with a side of global delay has been one of our major weaknesses as a hybrid. So, while what little I've read on Death Blossom's changes doesn't seem to be anything groundbreaking for giving us a more unique job identity, changes like this are all steps along of the way of achieving that.
Naturally, I'd be cool with a trait that extends debuff durations by default, too. Here's to hoping there's more than Frazzle and Distract in our future there.
Oh, and since I can't post on the OF with the whole "not subbed" thing going on, I saw a thread where someone was wanting a means to defend applied buffs from dispel effects. This is an old idea some of us tossed around in the past, but the thought was we could have a sort of Dummy or Barrier spell where, if a dispel effect struck us, be it single or mass, that effect would be eaten only. Self-target or not is a whole 'nother can of worms, but it's true our self-buff cycle is getting pretty lengthy as time goes on.
Violence good. Sexy bad. Yay America.
