See, your thinking exposes the attitude that most people have about PT, that he's three different characters.PT will never be High tier. While he his versatility is a huge plus. He lacks certain traits that prevent him from reaching higher tired levels.
By themselves none of the Pokemon are exactly high tier. If you were to break them down individually Squirtle would be on the low side of medium, Ivy the higher part of medium and Charizard in the Middle of both of them. The fact that all three of them have different play styles is a huge plus On top of the fact that each of them have at least three additonal attack styles
. But the fact you automatically change when one dies takes away from that as well as the time changing in battle takes. Character match up disadvantages and advantages make playing with PT extremely challenging. In some cases only one of three will actually have an advantage against you opponent while the other to easily get beat on. While in others you can wipe the floor with any of the three. If one could change aerially or if switching while you were in the air instantly sent you to the ground I could agree that he would be a top tier character. Even having a little control over where or when the Pokemon would appear would have greatly improved upon him.
Taking all of this into consideration He probably fall into the exact medium of the tier list if ranked properly.
Sakurai has again and again worked to make it painfully obvious, but people keep missing it, PT is one character, one character with the largest and most diverse range of moves in the game.
"Oh noes, I have to switch characterz, that suckz."
Saying that PT is three different characters is like saying that there are three different kinds of Marths, the B-button Marth, the aerial Marth and the ground Marth. That is wrong.
The true power of PT will only be unlocked when people stop viewing the pokemon seperately and begin playing them in a unified, synchonized machine.
