It's pretty entertaining, reading this. I like how you combine your arguments with sufficient insults so it gives off the illusion that you're right. If I am so uninformed about the manga, care to add manga scans to your arguments? Of course the possibility of Sakura going SM is there, but not as likely as her using Katsuyu as a summon.Saying Sakura not having the mark on her forehead like Tsunade is ridiculous because you are basing off of your opinion and not the manga or the nature of Sakura's character.Just because the characters of the manga have noted that Sakura has a big forehead and Tsunade has big forehead doesn't mean this was some sort of foreshadowing by kishi that Sakura's character will develop in a way that makes her a clone of Tsunade.Tsunade has blonde hair, blue eyes, large breast, and is a Senju.So are you telling me because "everything in Naruto is connected in a way" Sakura's hair will change from pink to blonde, her eyes from green to blue, she will go from flat chested to large breast, and eventually we will find out she has Senju blood? Again, your "everything in Naruto is connected in a way" statement is nonsense base on what we have seen from the manga.Sensei in there disciples are rarely alike.By your logic, Naruto should have imperfect Sage mode because Jiraiya was an imperfect sage;Right, because "everything in Naruto is connected in a way".Disciples have some characteristic of there sensei, but as a whole as seen in the manga, they have there own style and attributes.Onoki Dust releases and Mu's Dust releases is an example of that, as is Shikimaru telling an enemy shinobi that Shadow Paralysis Jutsu is an old name, as he called the jutsu Shadow Possession Jutsu during the destruction of the leaf arc.
As for Sage Mode, it seem you don't know anything about it.A prerequisite to being able to use senjutsu is that the user must have a large reservoir of chakra themselves in order to manipulate the natural energy.~You must be registered for see links
Yes, we have never seen a Shinobi collecting chakra in order to enter Sage Mode;That is because every single Sage Mode users shown has had large chakra reserve.This is a manga fact.Jiraiya like all the Sannin had large chakra reserves, so does Naruto, so does Hashirama and So does Kabuto.Sakura was known to have low chakra reserves which is why she would need to store her chakra up to had enough to enter Sage Mode.You just have to admit you are wrong kid.You don't know the facts of the manga.Saying Jiraiya didn't have large chakra when the manga and databooks clearly says he does, not knowing you need large chakra reserves to enter Sage Mode.Thinking that someone with Large chakra like Jiraiya wouldn't be somewhat drain of chakra after using just one summoning jutsu and a few mid level jutsu.You simply just uninformed on the manga.

There's no need for me to respond to this, if you're trying to be funny, sorry. I did not laugh.
