Re: Part 1 Naruto Tier List
The list is pretty accurate. Though I must say that splitting some characters into several stages is quite confusing and not really adding to the thread's clarity. Therefore I'll only refer to characters from the Sasuke retrival mission, since that's their newest state before the timeskip.
Nonetheless, nice work. It's a shame that your thread only received two pages of attention. Nowadays, where the only discussed characters seemingly are the higher tiers of the current arc, threads about part one characters are quite refreshing. However, there are some characters I'm not completely d'accord with.
In my opinion, Zabuza is totally out of place in the High Jounin tier. That's the tier where Gai and Kakashi reside; two characters that would most likely destroy him by all means. In their first encounter, Kakashi 'lost' due to a mistake; in their second one, however, Kakashi had control over the fight most of the time. And even though Haku took a hand in their fight, Zabuza was completely defeated. Now, that's not even Kakashi as he was at the end of part one. Like most characters, Kakashi greatly improved. Looking at Zabuza's databook-stats is actually enough. Though they're not very precise, a character with merely 30.5 points who lacks any special ability like a Kekkei Genkai does not belong to that tier. His Kirigakure no Jutsu, swordsmanship and silent killing traits are great and all, but from my point of view not enough to put him at that level. I think the first spot in the Mid Jounin tier would perfectly fit him.
Now that we talked about Zabuza; am I blind, or did you forget about Haku? In case you didn't, excuse me, in case you did: I'm not sure whether I'd put him into the High Chunin or the Low Jounin tier. On one hand, he was incredibly hyped by Zabuza as being even above himself. His Kekkei Genkai is also quite impressive. On the other hand, his stats are rather low. However, things like his impressive anatomical knowledge aren't considered there. His low scores at Taijutsu, Genjutsu and Riki (strength) don't say much, either, since he's no hand-to-hand combat type and even less a Genjutsu type. His intelligence of 4, however, is pretty remarkable, seeing how it's on the same level as Kakuzu's and 0.5 points superior to that of Hebi Sasuke, who has displayed great analytical and strategical feats. His extraordinary intelligence was once more proven when he was revived.  The same goes for his speed, which is only 0.5 points inferior to Hebi Sasuke's incredible speed. Not to mention his one-handed seals, that even Kakashi acknowledged.  Oh dear, Haku was a true prodigy. Thinking about all that, I think you should place him into the Low Jounin tier. The very fact that he was revived by Kabuto actually proves that he deserves that spot. Yep, Low Jounin.
I'm not completely sure about these two. Putting them into the Mid Jounin tier seems wrong to me. Of course, they received amazing power ups, Naruto has his huge Chakra reserves and Sasuke is in general incredibly skilled. But, like somebody already said before, the Jounin you put in that tier displayed a certain superiority to the rookies. It just seems not right to put them at Kurenai's and Asuma's level. Sasuke couldn't use any significant Sharingan techniques back then, and Naruto's Kyuubi Chakra was always somewhat restricted. If we take Kyuubi into account, we could simply move him up to the High Kage tier, since he could - in theory - unleash Kyuubi at any time. As I said, these two are tricky, but I'd at least move them down to Low Jounin.
Basically the same as above. Apart from the fact that he can't open all gates, not 'even' the 7th gate, he's only using them in very dicey situations, and can't keep them opened forever. It kind of bothers me to see a character only capable of using Taijutsu up there. On the other hand, with his gates opened and the lotus unleashed, he's pretty powerful. Lee after the timeskip is definitely Jounin level, but for this version of him I'd leave the choice up to you.
In my opinion Choji belongs to the Low Chunin tier. During the Chuunin examn, he was pretty much stomped by Dosu. His fighting-style is too one-sided, and his power-boosting pills carry too much of a risk.
Kiba likely belongs to the Low Chuunin tier. The only impressive thing he's shown in part one is his formidable speed, the good sense of smell and Soutourou/Garouga , a technique that is, according to the databooks, considered Jounin level. Though this is again a choice that I'm not completely sure about. It's up to you.
In case you do not know who that is: Orochimaru's second body, the guy that survived Kabuto's ordered 'free for all' in the prison. Even though that's his only feat, it's enough for me to put him at Genin/Chuunin level. However, since he's not of that much importance, adding him to the list is up to you.
That's it for now. As I said, the list is great, and apart from those characters I basically agree with the rest.
