My bad, it seems that I messed up with the skill Frost flame and Ice?Cold?Freezing? flame (dont remember exact name), the 2nd and much more used DoT skill of shamans, wich has a pretty good land rate compared to this Frost flame you were talking about. And yes, skill levels pretty much incorporate into the land rate of skills, the same like (or even more) lvl difference. 90% skill land rate I was talking about applies when all lvl requirements are met (this is based on ru classic discussions).
