the main problem with summoner is aetherflow,everything revolves around it. the dots take to long to cast on each mob,but bane is only good under aetherflow.deathflare is to erratic,about 255 of the time it want let me cast,even if i use the same combo to get it.ruin 3 is a joke,to expand to long to cast,can cast more ruin 2 that do more dmg in time to cat 1 ruin 3,unless of course you have trance on which of course mean you need aetherflow.so you spend your time waiting on ONE spell over and over.its use is over in an instant than back to waiting.
