Hunter x Hunter 2011

[Splash!]

Even if it's two now, it would still be 3 to 2, not such bad odds. However, even they know the odds are only getting worse. This doesn't make much sense if you ask me.

You make it sound like none of the squad captains even exist and they would be nothing more than cannon fodder if they were engaged simultaneously. Kite may have crushed a bunch of inconsequential ants but he didn't face a single one with nen powers (before Pitou). With Pitou having the other ants go through the awakening process, it becomes exponentially harder to rush in. While Netero & Co. may be able to dispatch them one by one (which seems like what they are planning), what makes you think they could take on all of them simultaneously together with the Royal Guards. You know what Morel said about a battle between nen users going either way applies to the Ants too, it isn't just a saving grace for the good guys.

Even before all of this however, you have to factor in what THEY know and don't. They DON'T know how strong the rest of the ants are (even the weak ones), because they can't even get close enough to the nest. They DON'T know that there are other royal guards around or not. All they know is that better ants hatch as the amount and quality of their food increases, and that the King is possibly a couple of months away of hatching. That and there being at least one ant as strong as Neferpitou. Given this, why would they go "Oh gee, lets just rush in now because we don't have a minute to spare" when they could inadvertently end up contributing to ants' food supply and screw the whole world over in the process. Only the viewer is aware of how rapidly things are unfolding, the characters themselves don't know jack shit. What you call 'taking their sweet time' is them trying to get better grasp of the situation (because they don't know much).

EDIT:

Even with Killua's warning, I still find it funny they seem to be far more careful and unhurried than Kite, despite their superior power. It makes Kite look all the worse.

Wait! Did you just say Kite looks worse for hurrying too much? Weren't you complaining about how he didn't just rush and deal with it all before Neferpitou hatched? Seems like whatever happens, he looks worse...
