Really cool Hero, it would be a really awesome Hero to play if it was in the game. :)

This concept is strange... In both forms he has 4k health at lvl 20, so he should be considered a tank. His human abilities are crazy OP (slow for 70% and silence for 2 seconds). Also his mount is stupid, because the default mount has 40% movement speed increase...

Some of the language you used isn't convencional, so I'm going to translate a few things... Passive- Basic attacks deal an AoE in a frontal cone and use 1 Fuel (Firebat's Mana) Passive - Activate to add a damage overtime in every ability and basic attacks. The duration of the passive is 5 seconds, but the damag overtime stays for 10 seconds. Need a Light? - Azmodan "All Shall Burn", but Firebat can move at 100% speed and can stop Iceblock. Nozzles - An AoE that deals damage...

Good concept, nothing to add.

I didn't understand any of his abilities... So his passive makes him pass through unpassable stuff when he activates it. When he has 2 charges he has 20% bonus move speed. His Q is some kind of skill shot AoE like Moonfire. His W increases his attack speed but decreases damage. His E works like Sonya's Whirlwind. His secondaries come from nowhere for some reason. His heroics turn in into different form that do something. Does he start at Whirlwind then grow into Storm or Tornado on...

Awesome Heroe! I imagine him as a perfect warrior against a strong engaging team, that can punish you hard. His passive can help midigate some damage from the enemy DPS and his W can help a friendly support heal his team before they die. His first heroic is perfect for small spaces in objecives like the Tributes in Cursed Hollow, but his second heroic is perfect to help allies channel powerful abilities like Chen's brew and heroic or Kael'thas Pyroblast. Again, AWESOME HERO, PERFECT...

3rd heroic: "Have S3x With Tim"- Increase move. and attack speed gradually for 2 seconds. After this explode with a big white flash, stunning all units nearby.

INDUCE MADNESS (D) is basicly Sylvannas Possession, but better, less cooldown, faster to use. You can simply put this in the enemy gate and get a free minion wave... seems too simple, compared to abthur (which spawns 1 locust every 15 seconds) you can spawn 7 minions in 0 seconds for 13 seconds every 15 seconds)

I know you are not part of any balancing team, but a 4 second cooldown on a minmum 25% heal is horrible. This combined with... ... can easily stop a lvl 20 pyroblast from having ANY damage at lvl 1. Not only that, but... ... can take out any enemy from a fight, because it deals enourmous amounts of damage PLUS, it stuns for 1 second. Then the heroics: When you say large prism I imagine an AoE the size of Void Prison, dealing 500 damage per second. This would be even more...
