8th ed characters

[Hatsgames]

I wouldn't mind everyones interpretation of the new 'characters on mounts' rules in the Warhammer 8th book.

Here is what I make of it:

I have a character, we will call him Bob.

Bob gets mounted on his shiny chariot.

Bob confers the Character trait to the chariot, and the chariot gives Bob the Chariot trait. They are one model according to the new 8th ed rules.

Chariots follows the rules for monsterous cavalry

Monsterous Cavalry follows the rules for monsters

So in the end we have a single model consisting of Bob and his pimpin ride (the chariot)
Bob's traits are: Character, chariot, and monster
Bob's chariots traits are identical

So...

Question 1: can Bob's pimpin chariot issue and recieve challenges now that it counts as a character?

Question 2: if so, what the hell is Bob up to while his chariot is handling his 'light work'?

Question 3: Does the Impact Hits rule stack so as to have Bob and the Chariot both do impact hits?

Thank you all!
