Mobility problem

Riot: We are going to tell you players that we don't like how super mobile champions aren't punished for their mobility, but we're going to just keep releasing super mobile champions that aren't punished for their mobility, instead of helping the immobile champions gain a place in this game.

New champion: super mobile? YES! deny it? NO! 70% movespeed bonus AND another gap closer/flash effect (it's 450 on tank form, longer range than flash which is 400).

"Oh, but his tank form is slow!" Having an ability to flash where you please (E) which also does damage based on how much max HP you have (It's basically a slightly shorter range kha'zix jump)... immobile? nope. Oh, and his ranged slow is delayed and easy to dodge right? hell... no.

"Oh, but it's squishy in non-tank form and will die IF you catch it!" Fizz doesn't build ANY tank items and that bastard still doesn't die IF you catch him, I know because I play him. So... catch him and he dies? nope.

"his tank form doesn't last long!" 22 seconds at level 7 is NOT a short duration... it's longer than nasus/renekton ults, and has better stats than their ults with shyv ult added to them.

Where's the punishment for this? It's random? Doesn't he have a sivir Q that slows everything it hits? that will put him in combat? that will let him kite until it procs then faceroll engage?
