It was bad on paper right off the bat anyway. I dunno where you go find theses "frost" ideas. And 5s freeze doesn't qualify for "auto win". You say you get auto win because your opponent is rooted, what makes you say that you weren't stucked to him like glue anyway ? Also possible that 1% gets diminishing returns like deadman's hand, not sure, let's say it doesn't. You're willing to sacrifice about 10% of your survavibility or damage for some random proc that might never come and even if it does no garantees it will help you at all. You need a stable, reliable toon, not something that shine once every full moon, and dies every single other day.
