short:
- Threat is now distributed blizzlike (almost)
long:
- Percent- and AP-Modifieres got add
- Threat is now propperly distributed through multiple enemies
- Most spells will cause initial threat in an amount equal to their SpellLevel
- Energize-Effects will now be treated like healing (threat-wise)
- Tanks got their missing +43% passive threat tacked on
- Paladins are still missing 'Salvation' and will not only cause half threat with healing (essentially 25% of the amount healed)
