hey jaedong i've been playing the past couple weeks using your guide in conjuction with the documentation it has been immensely helpful (answered every question i've had!). i've been playing caster druid following the guide lines you've layed out... im currently at the tail end of terror. something ive noticed that is worth mentioning i think and might be helpful for others. i find putting points into pleague avatar much more useful as an aoe than freezeing gale. Gale requires you to be in almost melee range (not a great aspect for a fairly squishy caster), not to mention hatred act 3 and up i found much more cold immune monsters than poison immune. However while using avatar im able to sit back comfortably behind my follower and summons and blanket the room in poion and fire off a few elementals and everything dies, an added benifit avatar adds damage to the summons poison flash attack, so essentially even more damage output.
Anyway just some feedback, again thanks for the guide.
