Dragon as a champion?

make a dragon as a champion kind like shyvana. i have ability ideas.

Passive: about 25% of attack damage to armor

R: He leaps forward into the air increasing movement speed and blowing a stream of fire into a movable area. After 4 seconds he dives down to a target and knock up enemies in a certain radius

E: Toggles between melee (using claws and teeth) and ranged breath weapon (he spits fire balls). it also changes abilities

Melee W: He spins around lashing his tail out knocking back enemies

Q: He lashes out just beyond standard attack range and bites a target dealing damage and dragging them back.

Ranged: W: He leaps forward breathing fire below him. lunges and leaves a trail of fire.

Q: He breaths a stream of fire that, at level one, lasts one second and gets increased to three seconds at level four. (to cancel recast. and it also slows him while casting. The fire stream can move like vel'koz's ult)

Personally i would really like dragon as a champion. It seems like something long overdue.

I'm not a good artist so i don't have concept art but model ideas. blue and silver. four legs two wings like the jungle dragon. in a way he looks regal/royal, more... slender in a way.

idk all of these are just my ideas :P. but is sounds cool to me ;).

I kinda like this name idea: Vlaximier, prince of beasts

all of this can be changed this is just my base ideas. Please vote and comment on what would make it better.
