Heroes of the Storm Build Guides
Does living Meteor travel through heros or stop at the first one hit? Seems very similar to pyroblast.
I love how the smash travels along enemies.
Living Meteor travels through targets and *could* hit all enemy heroes. The first target can steer it away from their team. Then, it will try to proceed to the next hero but likely won't make it in time due to slow turn speed.
I hadn't considered movement along Magma Fissure and I think that could be an interesting talent. His normal attack is a ranged fireball, but for targets along the fissure, his attack will travel through the fissure and erupt to strike the target, with very fast projectile speed.
The Fire Wall doesn't seem like it does enough to warrant being the trait. Traits are meant to be what defines the Hero from the others. Magma Fissure would be a defining Trait if you made it one and he used it as his primary short range mode of transport. You could even spice it up and give him a regen boost when traveling on it instead of the attack range boost. Imagine him healing from the gases or lava, although you would need to lower his Health it's quite high.
It could be something like.
Magma Fissure: Send out a Fissure to travel along. Restore 1.81(+0.31 per level) health per second while on the fissure. Lasts for 240 seconds.
Or
Move 20% faster along the fissure.
You could create a whole chain of fissures to move all sorts of places, but i'm getting carried away now for it not being my concept. Also get rid of the automatically collecting regen globes though. With Regeneration Master and his high health thats op.
I'm going to be stubborn regarding movement. I want Ragnaros to be quite powerful, but indeed he is totally vulnerable to targeted abilities. I also want to work on the interactivity of playing Ragnaros, since you don't have the decisions/gameplay regarding movement when playing him.
