I'm sure the completion times difference would make a lot of sense if you consider tidge and others are spending more time trying to survive than you. I wouldn't skip the power but I could understand not turning it on unless I was sure aggro was taken care of - even then it can strip aggro as mentioned earlier in the thread.
Again, even in the 8 ft scenario we are talking half debuffed targets for the majority. I dislike having to spam different targets with the exact same power to get my full debuff from this set, unlike any other debuff set. Jump in with VG, jump back out for Neuro, etc. Just messy silliness. I WANT to love this set, but that's why I brought it up - I wish it got some dev love.
