a Bone Dragon's hitbox could be a wee bit larger.

[Tryfaen]

These guys in Dragon Necropolis are like 30ft tall and 50ft long and have a hit box that is like 3 feet across.
Now im not requesting that the hitbox be made so big that i can slap the tip of the dragons tail but the hitbox could be a wee bit bigger.

We can't change this.

Just to add to what Rab said, it's something to do with the client that can't be altered, your concern has come up in the past. It's just one of those annoying things we have to deal with, another huge pain is the fact that Wiz can't completely customize AA's, he can merely alter the ones originally released on live.
