Not sure if there is still anyone out there but Recently I took a liking to Ice Lightning Mage but I've some questions. 1) +1 Attack Speed or 50% Buff Duration as inner ability? I've seen that the most "recent" thread has most of the users recommend 50% Buff Duration over +1 Attack Speed but I'm unsure how true is it for today. 2) Should I fret myself and fill up the Critical Rate area in Maple Union to achieve 100% Critical Rate? I understand that Critical Damage is the strong point of Ice Lightning Mage but should I worry much about other damage sources' critical rate like Elquines, Blizzard's Final Attack and maybe Thunderstorm, since Frozen Orb and Chain Lightning has higher innate critical rate? Is 75%~80% of Critical Rate sufficient?
