Update Info

There are some interesting and some worrying parts about it all.

I've heard claims of people on the test servers that fights which were previously easy now have become impossible. But who can trust those kind of tales of strangers?

This would be because mitigation has altered severely (not in the least because items worn on rings and around the neck no longer provide physical mitigation), amongst the fact that fighters have a reduced dps, ...

Mitigation

The base mitigation values of armor against an opponent of your level have been adjusted as follows: Heavy (32%), Medium (26%), Light (20%), Very Light (10%).
Mitigation scales up or down based on the con color of your attacker. That is, you mitigate progressively more damage of blue, green, and grey opponents, and progressively less against yellow, orange, and red opponents.
Mitigation is now shown as a numerical value instead of a percentage. The percentage is visible by mousing over the mitigation value on the Persona window.
Spell and item effects can now have a greater effect on your physical mitigation. You can mitigate a maximum of 80% of any physical damage type. This cap is higher against opponents that con grey.
Armor quality (Handcrafted, Treasured, Legendary, Fabled, or Mythical) has a greater impact on mitigation value than it did before.

Melee Damage

Melee damage bonuses for both auto-attack and combat arts are now calculated based on the attacker's strength.
The damage output of both players and NPCs should now increase more smoothly rather than receiving a sharp boost every ten levels.
Weapon quality (Handcrafted, Treasured, Legendary, Fabled, or Mythical) is now a greater factor in the damage potential of weapons.
Damage buffs only enhance auto-attack damage, not spells or arts.
The con of the target is now the primary determiner of your chance to hit or defend against attacks instead of skill. Skill buffs still have an effect, but they are treated more like a buff rather than the primary determiner.
Mages and Priests now gain 5 points per level in their offensive melee skills.

An important part of the update. But there is just too much to name, best check the update yourself.
