@RDarren:
I don't highly doubt that that would happen but it seem more KHR-ish when Tsuna's friends fought the Varia. I know Tamura wil do better than that. :\
The varia arc was a great arc though, I wouldn't place the rest of KHR with that arc, it's like how I wouldn't place part 1 of Naruto to part 2 or The beginning of Bleach till the end of soul society with the rest of the series when talking about the quality of it
I don't see how you could keep the rest of them in with the fighting if you didn't do this, since it seems like demons are gonna become more and more involved with the story, the ishiyama cast needs some sort of power ups so they can fight the lesser guys wile oga, Toujou, and aoi fight the big bads, and I'm sure the Rokkesei will get the same treatment
my guess is guys who just fight with there own strength will be, Oga, Toujou, Kunieda, Inzuma, Miki, and Shizuka everyone else will have magical items that fit their personalities/hobbies/weapons they already use
granted this is just my thinking I have no proof nor do I claim to, and I'm bad at guessing what will happen in mangas too so I'm definitely not 100% sure on this
