You said yourself that Acnologia wasn't picked up, so they have no reason to suspect he's coming. That one Spriggan would be taken out by the top 4 (not traitor) Wizard Saints is hardly suspicous after all.

Unless Lucy slept "off-screen", she's been awake for more than 28 hours already and in that time almost got killed twice, fought with Marin and had another shock and emotional strain when Natsu almost died. All cases that put a lot of adrenaline through your body which usually has a backlash in the form of exhaustion. At some point her body just had to give out no matter if she wants to rest or not.

As for traps: What kind of traps would Lucy be able to set? The only "trap" she's ever set was digging a hole and covering it up with twigs. And I don't see how Celestial Spirits are good at laying traps either. Not to mention that any trap Lucy would make would be next to if not outright useless against Spriggan level enemies and Acnologia.

If there's anyone present to make traps it'd be Droy, who could scatter and enchant some plants, Cana who could make traps with her cards, Freed if he's sufficiently recovered to write more Jutsu Shiki around the place or Makarov who we know to have a big variety of spells available or even Max who's shown some technical genius in inventing the radar and a few other things. So against all those people why is it Lucy who should make traps in your opinion?

"You don't understand what i'm going on do you two."

If you are not looking for excuses to hate on Lucy and ignore anything and anyone else, then yes I do not understand you.

Because if you were going on about the situation, you'd also complain about the other people back in the guild, but you only complain about Lucy and nobody else.
