Rolling Magma

Not being able to hit opponents right in front of you makes it the worst feeling skill there is in the game.
My plan was to go for fire druid with Rolling Magma and Volcano as the main combo with support from Flame Wall and Frost Bomb. But you can not do it because you can't stay near opponents to keep them on Volcano because your Rolling Magma won't hit them and won't trigger the Volcano.
Being swarmed by some mobs and not being able to hit them also feels really bad.
