Itachi has high chakra reserves.

Cool...

Why does he need a lot of chakra when he can just finish his opponent off with one move? :|

Powerful chakra=/=lots of chakra.

Also, Itachi didn't use Amaterasu five times. He used it once, used it again which set fire to the trees because they spread based on his line of sight, and then used Kagutsuchi on Sasuke. Yata Mirror also wouldn't consume chakra as it is a spiritual weapon he holds with Susano'o, not a jutsu.

Summoning a Crow Clone and summoning a crow aren't that impressive either, especially the latter being something Kid Naruto could do with his chakra disturbed by Orochimaru's seal on top of Minato's.

Riker, is that you?! I WAS LOOKING EVERYWHERE FOR YOU!

The real reason why itachi stamina is considered low is because he didn't like to fight hence why he tries to end the fight fast he takes no pleasure in violence and loathed it

i think that he was gifted with the will and body of uchiha and was strong and that yea the illness weakened him to the point where using certain techniques made the condition worse but i also think that all the other stuff like giving him hashi cells and if he had a jinchuriki would have prolonged his life because thats more closer to god like powers generally the less the common rules of reality apply to you such as sickness lets look at obito for example half of him was crushed he would have been in a physically weakened state when madara got him he was still able to be infused with the cells and managed to live what are the chances of that occurring oro had issues getting one child to survive but madara got obito to. Those would be amazing odds except i dont think it was odds i think it was much less of a gamble based on his lineage kabuto later did the same thing with madaras body and there was no aparent rejection from this process nor did it get over written so they must be naturally able to combine with uchiha dna which i surmise is because their distant reletives that they are compatable, such as a distant family member being able to donate organs and be much closer of a match than anyone else.
