First impresion about Sett

So I cant say I played him to much pvp, I tested him in practice tool a lot tho and had few games, so there's the main things I want to say about him. He's acutally really fun to play, probably the most fun champion released in new years His shield can be a little too much, and that may compensate other things I'm about to say, but still, those should be fixed, a huge shield will not mean much. He have no way to escape or fight ranger, even with Q, that 30% movement speed barely help him to get close to chase a melee champion, a ranged champion will never get even in his E range by any other reason than that person sucks playing their champion and do not know to keep distance. His only movement is extremly conditioned, if you chase someone and he step in a bush or you lose vision you have nothing, also if you are the one chased you can't just run away, he's basically like xin zhao if xin would be able to E only enemy champions. His E range seems too short, I didn't say it need a huge radius increase, but if he will not get more movement speed in his own kit without things like deadman plate in combination with other 2-3 items just to chase someone, I think an +25-50 range is really needed.

Not to say, you mostly want to catch at least an enemy on each side of your E, so in tf you will not aim for the closest enemy, and instead you want to go in the middle of them before pessing E, and as much as I want to say his R can do it, his R seems more like an execute, or his only way to escape once he ingage, because he can't get out otherwise than jumping away with a low hp enemy, he can't use Q to just run or smth if he's focused, he can't really fight if he's not in melee, so what exactly can he do against someone like Caitlyn or cassiopeia, even if he would build full tank he would die before even reaching a punch on them, not to say, again, realistic he can't just run away from anyone, despise his good movement speed a dash or a slow will completly outmatch him, not to say hard cc.
