Sorc build?

both of you guys are missing the point fires potential is just as strong as cold orb coverage = hydra coverage at diff levels, fire ball is the true killer, and insolence in your diagrams... HONESTLY WHO THE FUCK STAYS STILL AND CASTS HYDRAS LIKE THAT, stop dueling noobs, hydra placement is purely deffensive while fball is offensive, thus in equivlance to orb coverage, so what orb has greater instant area coverage, with a fire sorc you make a mistake... well your toast literally
