well i wasn't aware about that guide untill now ( i did a search on forums) . i was away for a few years .i didn't know what you were talking about . i'm sory if i offended you
lightning-poison and lightning-fire combos were the mainstream for melee sorc when i first quit playing Median . they were the obvious choices for experienced players ; Cold tree was used only for casters and hybrids with summons (i still stick to those ideas , there are better trees for a (pure) melee sorc than cold )
