I've noticed that most people (including the super duper capped) use this spell almost exclusively in DR arena and to quest with , fantastic damage factors, great AvD, only 4 mana and a godsend for the early levels. In DR arena I use 903 and 910 but for everything else my go to is steam. For those above lvl 50 that mainly use steam what would it take for you to regularly switch to the other elements?
Also if the acension skill Mana Adept (reduces spell cost) becomes a thing would that tempt you to use Hurl Boulder or Major Shock more often?
