Okay so both the icy-veins and wowhead guides recommend either the following talent setups:
Glacial Advance + Frostscythe
or
Obliteration + Runic Attenuation
They have tailored their guides towards taking either combination of the above. However, if you look at warcraftlogs, the top performing Frost DK's are consistently taking Glacial Advance + Runic Attenuation.
Could someone explain to me why, and also how are both guides (which are generally fairly reliable sources) all wrong?
