darkassasin, you can't just steamroll through this game. you have to pick up skills that help you in your fight. There are skills in each class's skill tree that make a healing mob's life miserable ;)
The two missing talents in ice and holy trees could be as followed: Ice talent > 2/2 increase freeze and slow time of all ice spells by 2 seconds. holy talent > 2/2 Gain 5% damage done as health. THese are just ideas, I don't know why only fire has a talent there :/
actually when you are being juggled u can control yourself in the air with the arrow keys. however MAKE SURE you know which way you're facing so that you float away from the mobs and not towards them
