It was cool and what ? Puting him above Hashirama Madara and much more is just retarded. Kakashi has 4 elements i dont see u to put him in top 5 ?
Dude... you sound like one of those crazy homeless people w/ an aluminum foil hate screaming about the world ending. Please submit some actual proof anyone putting Sarutobi above all other ninja, because I haven't seen it. I think you are probably just one of those guys who constantly touted the 3rd was all hype and was fodder, and now that he finally showed an impressive feet you are feeling a bit butt-hurt about it... or you're just a troll.
Basically Hiruzen just showed us something never before seen by any other ninja outside Nagato, so his fans have the right to say it brings cadence to the claim of him being the God of Shinobi
of his time and certainly makes his "Professor" title as one who mastered all Konaha's jutsu valid.
I mean just think about the possibilities of how he could combine elemental attacks w/ just 2 clones ala Naruto/Sasuke. And no you don't need proof showing him do this, because Kakashi has told us if two ninja match output of two combine-able elemental jutsus they will come together to make a stronger one. Matching output would be as easy as taping the top of your head and rubbing your stomach at the same time for 2 shadow clones. This is NOT the same as KKG, but it's still a powerful tool.
All this ranking non-sense you're spouting is meaningless. There is no universal strongest ninja top 10, a large majority of naruto fans would agree with, and for good reason. That being the case,
all top 10/5/3's are invalid, and purely a case of
personal opinion.
BTW... Kakashi has 3 elements (lightning, water, and earth), this is manga fact. The 4th element (fire, I think?) is pure anime filler.
