Sorry, Kraco, I think youīre unfair and harsh on Kite.

He lost an arm due to protecting Gon and Killua. And thatīs where his fight against Pitou started. Most of the Spiders would be significantly weaker without both arms intact. Hell, imagine C....whatshisname, the leader without both arms. He wouldnt be able to use his strongest power.
Fact is, Kite was at a severe disadvantage against Pitou.
Secondly, I think youīre underestimating Pitou (as a consequence of your unwillingness to accept the Chimera antsī incredible powers) and overestimating the Spiders and Netero and company.

Itīs best to accept that the chimera Ants just are THAT fucking strong. If that makes any sense, well, letīs hope the anime clears up on that. Even if it doesnīt, itīs pretty simple to understand: A standard chimera ant is made of 2 animals being eaten and processed by the queen (using bs-numbers here). One of the higher ranks like the first intelligent, winged chimera ant is made of 100 living beings. Then say the royal guard is made of 1000 people. And the king is mde of 10000 people (add a zero to each of those numbers, if necessary). What Iīm trying to say is: These high ranking chimera ants are a simple culmination of power. There is nothing clever about it. 1+1 = 2. 2+1 = 3. 100 x 1 = 100. Itīs the most simple of mathematics. A single, normal human being might be nothing, but concentrate the power of 1000 normal human beings and they might have a shot against someone like Netero.

Two complaints being left:
1.) Pitou being a "noob": I donīt think itīs that difficult to accept that all Chimera Ants are natural born fighters. Most animals are born with certain abilities. Especially insects.
2.) Chimera ants using nen, and Pitou being able to use it without having met nen-users. No idea. Itīs either my own theory of Chimera ants being natural nen users, proven by the Phagogenesis ability, or thereīs something else.

Either way: Kite didnīt give me the impression of being weak. Pitou gave me the impression of being a monster, in the sense the Uborgin never was.
